VW Jetta GLS

VW Scirocco

Introduction to the Golf, Jetta and Scirocco Introduced in 1974, the new VW Golf soon established itself as a market leader in its class. Together with the mechanically similar Scirocco Sports Coupe, these vehicles set new standards of design integrity which have since been emulated by many of the world’s leading motor manufacturers. Following on the success of the Golf and Scirocco, a more traditional notchback Saloon, the Jetta, was introduced in 1980 to conform to changing market trends and a demand for a conventionally styled ‘3-box’ saloon in the middle range. To further enhance

the

appeal

of these

vehicles

a

convertible version of the Golf, together with a

Pick-up utility vehicle, have also been added to the model line-up. All models feature a transversely mounted engine/transmission configuration with frontwheel-drive and the now almost universally accepted ‘conventional’ independent front, semi-independent rear suspension layout. A wide range of trim and equipment options are also available.

Safety First! o-s Working on your car can be dangerous. This page shows just some of the potential risks and hazards, with the aim of creating a safety-conscious attitude.

General hazards Scalding ¢ Don’t remove the radiator or expansion tank cap while the engine is hot. ¢ Engine oil, automatic transmission fluid or power steering fluid may also be dangerously hot if the engine has recently been running.

Burning ¢ Beware of burns from the exhaust system and from any part of the engine. Brake discs and drums can also be extremely hot

immediately after use.

Crushing ¢ When working under or near a raised vehicle, always supplement the jack with axle stands, or use drive-on ramps. Never venture

under a car which is only supported by a jack. ¢ Take care if loosening or tightening hightorque nuts when the vehicle is on stands. Initial loosening and final tightening should be done with the wheels on the ground.

¢ Mains voltage is also dangerous. Make sure that any mains-operated equipment is correctly earthed. Mains power points should be protected by a residual current device (RCD) circuit breaker.

Fume or gas intoxication e Exhaust fumes are poisonous; they often contain carbon monoxide, which is rapidly fatal if inhaled. Never run the °°, engine ina confined space such as a garage with the doors shut. e Fuel vapour is also ~ poisonous, as are the vapours from some cleaning solvents and paint thinners.

ca

Poisonous or irritant substances e Avoid skin contact with battery acid and with any fuel, fluid or lubricant, especially antifreeze, brake hydraulic fluid and Diesel fuel. Don’t syphon them by mouth. If such a substance is swallowed or gets into the eyes,

seek medical advice. e Prolonged contact with used engine oil can cause skin cancer. Wear gloves or use a barrier cream if necessary. Change out of oilsoaked clothes and do not keep oily rags in your pocket. e Air conditioning refrigerant forms a poisonous gas if exposed to a naked flame (including a cigarette). It can also cause skin burns on contact.

Fire

Asbestos

¢ Fuel is highly flammable; fuel vapour is explosive. ¢ Don’t let fuel spill onto a hot engine. ¢ Do not smoke or allow naked lights (including pilot lights) anywhere near a vehicle being worked on. Also beware of creating sparks (electrically or by use of tools). ¢ Fuel vapour is heavier than air, so don’t work on the fuel system with the vehicle over an inspection pit. e Another cause of fire is an electrical overload or short-circuit. Take care when repairing or modifying the vehicle wiring. ¢ Keep a fire extinguisher handy, of a type suitable for use on fuel and electrical fires.

e Asbestos dust can cause cancer if inhaled or swallowed. Asbestos may be found in gaskets and in brake and clutch linings. When dealing with such components it is safest to assume that they contain asbestos.

ae

Electric shock “k ©

¢ Ignition HT voltage canbe

dangerous,

a

let especially to Z people with heart problems or a _pacemaker. Don’t work on or near the ignition system with the engine running or the ignition switched on.

Special hazards Hydrofluoric acid e This extremely corrosive acid is formed when certain types of synthetic rubber, found in some O-rings, oil seals, fuel hoses etc, are exposed to temperatures above 400°C. The rubber changes into a charred or sticky substance containing the acid. Once formed, the acid remains dangerous for years. If it gets onto the skin, it may be necessary to amputate the limb concerned.

¢ When dealing with a vehicle which has suffered a fire, or with components salvaged from such a vehicle, wear protective gloves and discard them after use.

The battery ¢ Batteries contain sulphuric acid, which attacks clothing, eyes and skin. Take care when topping-up or carrying the battery. ¢ The hydrogen gas given off by the battery

is highly explosive. Never cause a spark or allow a naked light nearby. Be careful when connecting and disconnecting battery chargers or jump leads.

Air bags e Air bags can cause injury if they go off accidentally. Take care when removing the steering wheel and/or facia. Special storage instructions may apply.

Diesel injection equipment e Diesel injection pumps supply fuel at very high pressure. Take care when working on the fuel injectors and fuel pipes. Warning: Never expose the hands, face or any other part of the body to injector spray; the fuel can penetrate the skin with potentially fatal results.

Remember... DO

DON’T

¢ Do use eye protection when using power tools, and when working under the vehicle.

e Don’t attempt to lift a heavy component which may be beyond your capability — get assistance.

© Do wear gloves or use barrier cream to protect your hands when necessary.

* Do get someone to check periodically that all is well when working alone on the vehicle. © Do keep loose clothing and long hair well out of the way of moving mechanical parts. ¢ Do remove rings, wristwatch etc, before

working on the vehicle — especially the electrical system. ¢ Do ensure that any lifting or jacking equipment has a safe working load rating adequate for the job.

¢ Don’t rush to finish a job, or take unverified short cuts.

e Don’t use ill-fitting tools which may slip and cause injury.

¢ Don’t leave tools or parts lying around where someone can trip over them. Mop up oil and fuel spills at once.

¢ Don’t allow children or pets to play in or near a vehicle being worked on.

og Roadside Repairs

Identifying leaks Puddles on the garage floor or drive, or obvious wetness under the bonnet or underneath the car, suggest a leak that needs investigating. It can sometimes be difficult to decide where the leak is coming from, especially if the engine bay is very dirty already. Leaking oil or fluid can also be blown rearwards by the passage of air under the car, giving a false’ impression of where the problem lies.

o10 Roadside Repairs

Jacking and towing Jacking The jack supplied with the car is intended only for wheel changing in an emergency. For any other work it should be supplemented by axle stands or blocks. Do not venture under the car when it is supported solely by a jack. To change a roadwheel, first remove the spare wheel and tool kit from the well in the rear compartment (photo) on all models except the Pick-up. Apply the handbrake and chock the wheel diagonally opposite the one to be changed. Make sure that the car is positioned on firm level ground. Lever off the bolt caps or hub cover and slightly loosen the wheel bolts with the spanner provided. Raise the jack and locate it under the reinforced area in the sill below the wedge-shaped mark (photo). Raise the jack until the wheel is free of the ground, then unscrew the bolts and withdraw the roadwheel. Locate the spare wheel on the hub and tighten the bolts lightly. Lower the jack, then

finally tighten the wheel bolts and refit the hub cover or bolt caps. Remove the chocks and refit the wheel and tool kit to the rear compartment.

wheels suspended. Towing by suspending the rear of the vehicle is not recommended, and must never be attempted with automatic transmission or Pick-up models.

Towing Towing eyes are provided at the front and rear of the car beneath the bumpers (photos), except on the Pick-up which only has a front towing eye. Providing a fault has not developed in the manual gearbox or final drive, the vehicle may be towed on its four wheels. The same rule applies to models with automatic transmission but the car may only be towed in a forward direction at speeds up to 30 mph for a maximum of 30 miles. If these conditions cannot be met, it is possible to remove

both driveshafts,

withdraw

the CV

joints, then refit the CV joints only together with their rubber gaiters to the hubs. Alternatively, tow the vehicle with the front

Routine Maintenance 0-1:

Tyre condition and pressure It is very important that tyres are in good condition, and at the correct pressure - having a tyre failure at any speed is highly dangerous. Tyre wear is influenced by driving style - harsh braking and acceleration, or fast cornering, will all produce more rapid tyre wear. As a general rule, the front tyres wear out faster than the rears. Interchanging the tyres from front to rear ("rotating" the tyres) may result in more even wear. However, if this is completely effective, you may have the expense of replacing all four tyres at once! Remove any nails or stones embedded in the tread before they penetrate the tyre to cause deflation. If removal of a nail does reveal that

the tyre has been punctured, refit the nail so

that its point of penetration is marked. Then immediately change the wheel, and have the tyre repaired by a tyre dealer. Regularly check the tyres for damage in the form of cuts or bulges, especially in the sidewalls. Periodically remove the wheels, and clean any dirt or mud from the inside and outside surfaces. Examine the wheel rims for signs of rusting, corrosion or other damage. Light alloy wheels are easily damaged by "kerbing" whilst parking; steel wheels may also become dented or buckled. A new wheel is very often the only way to overcome severe damage.

New tyres should be balanced when they are fitted, but it may become necessary to rebalance them as they wear, or if the balance weights fitted to the wheel rim should fall off. Unbalanced tyres will wear more quickly, as will the steering and suspension components. Wheel imbalance is normally signified by vibration, particularly at a certain speed (typically around 50 mph). If this vibration is felt only through the steering, then it is likely that just the front wheels need balancing. If, however, the vibration is felt through the whole car, the rear wheels could be out of balance. Wheel balancing should be carried out by a tyre dealer or garage.

If you sometimes have to inflate your car’s tyres to the higher pressures specified for maximum load or sustained high speed, don’t forget to reduce the pressures to normal afterwards.

oe12 ROutINe Maintenance Maintenance is essential for ensuring safety and desirable for the purpose of getting the best in terms of performance and economy from your car. Over the years the need for periodic lubrication has been greatly reduced if not totally eliminated. This has unfortunately tended to lead some owners to think that because no such action is required

the items either no longer exist, or will last forever. This is certainly not the case; it is essential to carry out regular visual examination as comprehensively as possible in order to spot any possible defects at an early stage before they develop into major expensive repairs.

Fig. 4.1 Transistorized ignition components (Sec 1)

system comprise a battery, coil, distributor and spark plugs; the distributor is driven by a skew gear in mesh with the intermediate shaft of the engine. To enable the engine to run correctly, it is necessary for an electrical spark to ignite the fuel/air mixture in the combustion chamber at exactly the right moment in relation to engine speed and load. The ignition system is based on feeding low tension voltage from the battery to the coil, where it is converted to high tension voltage. The high tension voltage is powerful enough to jump the spark plug gap in the cylinders many times a second under high compression, providing that the system is in good condition. With the contact breaker type, the ignition system is divided into two circuits, the low tension circuit and the high tension circuit. The low tension (sometimes known as the primary) circuit consists of the battery, lead to

the ignition switch, lead from the ignition switch to the low tension or primary coil windings (terminal +) and the lead from the low tension coil windings (coil terminal - ) to the contact breaker points and condenser in the distributor. The high tension circuit consists of the high tension or secondary coil

spark occurs at just the right instant for the particular load at the prevailing engine speed. The ignition advance is controlled both mechanically and by a vacuum-operated system. The mechanical governor mechanism comprises two weights which move out from the distributor shaft as the engine speed rises due to centrifugal force. As they move outwards they rotate the cam relative to the distributor shaft, and so advance the spark. The weights are held in position by two light springs and it is the tension of the springs which is largely responsible for correct spark advancement.

in the following

Low tension voltage is changed

in

the coil into high tension voltage by the opening and closing of the contact breaker points in the low tension circuit. High tension voltage is then fed via the carbon brush in the centre of the distributor cap to the rotor arm of the distributor, and each time it comes in line with one of the four metal segments in the cap, which are connected to the spark plug leads, the opening and closing of the contact breaker points causes the high tension voltage to build up, jump the gap from the rotor arm to the appropriate metal segment, and so via the spark plug lead to the spark plug, where it finally jumps the spark plug gap before going to earth. The transistorized ignition system functions in a similar manner but an electronic sender and points the contact unit replaces condenser in the distributor, and a remotely mounted electronic switch unit controls the coil primary circuit. On some models the system incorporates a digital idle stabilizer (DIS) which automatically advances the ignition timing during idling when the engine experiences additional loads, for example electrical certain’ on switching when components.

On fuel injection models, the distributor rotor arm incorporates a centrifugal cut-out which effectively governs the engine to a maximum speed of approximately 7000 rpm (photo).

If it is not within the specified limits decrease the points gap to increase the dwell angle, or increase the points gap to decrease the dwell angle. 8 Refit the dust cover, rotor arm, distributor cap and interference screen if fitted together with the low tension leads, then check the dwell angle with the engine running (if possible). 9 Check and if necessary adjust the ignition timing as described in Section 11.

1 The condenser is fitted in parallel with the contact points. Its purpose is to reduce arcing between the points and also to accelerate the collapse of the coil low tension magnetic field. A faulty (short-circuited) condenser can cause the complete failure of the ignition system, as the points will be prevented from interrupting the low tension circuit. An open-circuited condenser will cause misfiring or starting difficulties, and rapid burning of the points. 2 To test the condenser, remove the distributor cap and rotate the engine until the contact points are closed. Switch on the ignition and separate the points with a screwdriver. If this is accomplished by a strong blue flash, the condenser is faulty (a weak spark is normal). 3 A further test can be made for shortcircuiting by removing the condenser and using a test lamp, battery and leads connected to the condenser supply terminal and body. If the test lamp lights, the condenser is faulty. 4 The simplest test is to substitute a new unit and check whether the fault persists. 5 To remove the condenser, remove the distributor as described in Section 9 and clamp it lighty in a vice. 6 Remove the cap, interference screen (if

fitted), rotor arm and dust cover. 7 Disconnect the low tension lead from the connector block. 8 Remove the retaining screw and withdraw the condenser and connector block from the distributor. 9 Refitting is a reversal of removal.

Car. 5 If the system develops a fault and it is necessary to tow the car with the ignition key switched on, the wiring must be disconnected from the TCI-h switch unit. 6 Do not under any circumstances connect a condenser to the coil terminals. 7 Take care to avoid receiving electric shocks from the HT system.

Remove the distributor body sealing washer and fit a new one on refitting. 9 To refit the distributor first check that the oil pump lug (visible through the distributor aperture) is set parallel to the crankshaft (Fig. 4.7). Check that the TDC ‘O’ mark is still aligned. 10 Set the rotor arm to the position noted in paragraph 8, align the distributor body and cylinder block marks and insert the distributor. As the gears mesh, the rotor will turn anti-clockwise and point to the previously made mark. 11 Refit the clamp and tighten the bolt. Reconnect the vacuum hose(s), and low tension lead or multi-plug (as applicable). 12 Refit the TDC sensor or blanking plug, and the distributor cap, then reconnect the

Note: Accurate ignition timing is only possible using a stroboscopic timing light, although on some models a TDC sender unit is located. On the top of the gearbox casing and may be used with a special VW tester to give an instant read-out. However, this tester will not normally be available to the home mechanic. For initial setting-up purposes of the conventional ignition system, the test bulb method can be used, but this must always be followed by the stroboscopic timing light method.

loosen the clamp retaining bolt and turn the distributor body anti-clockwise to advance and clockwise to retard the ignition timing. 17 Gradually increase the engine speed while still pointing the timing light at the timing

marks. The mark on the flywheel (or driveplate) or pulley should appear to move opposite to the direction of rotation, proving that the centrifugal weights are operating correctly. If not, the centrifugal mechanism is faulty and the distributor should be renewed. 18 Accurate checking of the vacuum advance (and retard where fitted) requires the use of a vacuum pump and gauge. However, providing that the diaphragm unit is serviceable, the vacuum hose(s) firmly fitted, and the internal mechanism not seized, the system should work correctly. 19 Switch off the engine, remove the timing light and tachometer, and refit the vacuum hose (where applicable).

1 The coil is located on the bulkhead in the engine compartment, and it should be periodically wiped clean to prevent high tension voltage loss through possible arcing (photo). 2 To ensure the correct HT polarity at the spark plugs, the coil LT leads must always be connected correctly. On the conventional ignition system the LT lead from the distributor should be connected to the negative (-) terminal on the coil. Incorrect connections can cause bad starting, misfiring, and short spark plug life. 3 Complete testing of the coil requires special equipment, however if an ohmmeter is available, the primary and secondary winding resistances can be checked and compared with those given in the Specifications.

1 The correct functioning of the spark plugs is vital for the correct running and efficiency of the engine. It is essential that the plugs fitted are appropriate for the engine, and the suitable type is specified at the beginning of this chapter. If this type is used and the engine is in good condition, the spark plugs should not need attention between scheduled replacement intervals. Spark plug cleaning is rarely necessary and should not be attempted unless specialised equipment is available as damage can easily be caused to the firing ends. 2 The condition of the spark plugs will also tell much about the overall condition of the engine. 3 If the insulator nose of the spark plug is clean and white, with no deposits, this is indicative of a weak mixture, or too hot a plug.

indicative that the mixture is too rich. Should the plug be black and oily, then it is likely that the engine is fairly worn, as well as the mixture being too rich. 5 If the insulator nose is covered with light tan to greyish brown deposits, then the mixture is correct and it is likely that the engine is in good condition. 6 The spark plug gap is of considerable importance, as, if it is too large or too small, the size of the spark and its efficiency will be seriously impaired. The spark plug gap should be set to the figure given in the Specifications at the beginning of this Chapter. 7 To set it, measure the gap with a feeler gauge, and then bend open, or close, the outer plug electrode until the correct gap is achieved. The centre electrode should never be bent as this may crack the insulation and cause plug failure, if nothing worse. 8 Always tighten the spark plugs to the specified torque. 9 Periodically the spark plug leads should be wiped clean and checked for security.

14 Thermo-pneumatic valve description and testing

EN » rN

1 Some carburettor engine models are equipped with a thermo-pneumatic valve which regulates the ignition vacuum advance during the warm-up period in order to improve cold driving performance. 2 On early 1.6 litre engines with automatic transmission the hoses are routed as shown in Figs. 4.10 and 4.11. With the engine cold, there is no vacuum

advance on the 55 kW engine,

and vacuum advance only above approximately 2000 rpm on the 63 kW engine. Full vacuum advance is available when the valve opens, ie at normal operating temperature.

Fault finding - ignition system By far the majority of breakdown and running troubles are caused by faults in the ignition system, either in the low tension or high tension circuit. There are two main symptoms indicating ignition fault. Either the engine will not start or fire or the engine is difficult to start and misfires. If it is a regular misfire, ie the engine is only running on two or three cylinders, the fault is almost sure to be in the secondary, or high tension circuit. If the misfiring is intermittent, the fault could be in either the high or low tension circuits. If the car stops suddenly or will not start at all it is likely that the fault is in the low tension circuit. Loss of power and overheating, apart from faulty carburation settings, are normally due to faults in the distributor or incorrect ignition timing.

Engine fails to start (conventional and transistorized systems) 1 If the engine fails to start and the car was running normally when it was last used, first check there is fuel in the petrol tank. If the engine turns over normally on the starter motor and the battery is evidently well charged, then the fault may be in either the high or low tension circuits. First check the HT circuit. If the battery is known to be fully charged, the ignition light comes on, and the starter motor fails to turn the engine, check

the tightness of the leads on the battery terminals and the security of the earth lead to its connection to the body. It is quite common for the leads to have worked loose, even if they look and feel secure. If one of the battery terminal posts gets very hot when trying to work the starter motor, this is a sure indication of a faulty connection to that terminal. 2 One of the most common reasons for bad starting is wet or damp spark plug leads and distributor. Remove the distributor cap. If

condensation is visible internally dry the cap with a rag and wipe over the leads. Refit the

cap. 3 If the engine on models fitted with conventional ignition still fails to start, check that current is reaching the plugs by disconnecting each plug lead in turn at the spark plug end. Hold the end of the cable with an insulated tool about 3/16 in (5 mm) away from the cylinder block, then spin the engine on the starter motor. 4 On engines with transistorized ignition remove each plug in turn and earth it to a suitable part of the engine with the HT cable connected. Spin the engine on the starter motor.

5 Sparking at the cables or plugs should be fairly strong, with a regular blue spark. If necessary remove the plugs for cleaning and regapping. The engine should now start.

Engine fails to start (conventional system only) continuation 6 If there is no spark at the plug leads, take off the HT lead from the centre of the distributor cap and hold it to the block as

before. Spin the engine on the starter once more. A rapid succession of blue sparks between the end of the lead and the block indicates that the coil is in order and that the distributor cap is cracked, the rotor arm faulty or the carbon brush in the top of the distributor cap is not making good contact with the rotor arm. 7 If there are no sparks from the end of the lead from the coil, check the connections at the coil end of the lead. If this is in order start checking the low tension circuit. Commence by cleaning and gapping the points (Section 2). 8 Use a 12 volt voltmeter, or a 12 volt bulb and two lengths of wire. With the ignition switch on and the points open test between

the low tension wire to the coil (it is marked - )

and earth. No reading indicates a break in the supply from the ignition switch. Check the connections at the switch to see if any are loose. Refit them and the engine should run. A reading shows a faulty coil or condenser or broken lead between the coil and the distributor. 9 Remove the condenser from the distributor body but leave the wiring connected. With the points open, test between the moving point and earth. If there now is a reading then the fault is in the condenser. Fit a new one and the fault is cleared. 10 With no reading from the moving point to earth, take a reading between earth and the negative (-) terminal of the coil. A reading here indicates a broken wire which must be renewed between the:coil and distributor. No reading confirms that the coil has failed and must be renewed. For these tests it is sufficient to separate the contact breaker points with a piece of paper. 11 If the engine starts when the starter motor is Operated, but stops as soon as the ignition key is returned to the normal running position the ballast resistor may have an open-circuit.

Connect a temporary lead between the coil positive (+) terminal and the battery positive (+) terminal. If the engine now runs correctly, renew the resistor. Note that the ballast resistor or resistive wire must not be permanently bypassed otherwise the coil will overheat and be damaged.

Engine misfires (conventional system only) 12 If the engine misfires regularly, run it at a fast idling speed. Pull off each of the plug Caps in turn and listen to the note of the engine. Hold the plug cap in a dry cloth or with a rubber-glove as additional protection against a shock from the HT supply.

Ignition system 4¢9 Ce

13 No difference in engine running will be noticed when the lead from the defective circuit is removed. Removing the lead from one of the good cylinders will accentuate the misfire. 14 Remove the plug lead from the end of the defective plug and hold it about 3/16 in (5 mm) away from the block. Restart the engine. If the sparking is fairly strong and regular, the fault must lie in the spark plug.

Engine misfires (conventional and transistorized systems) 15 The plug be cracked, away, giving jump. Worse

may be loose, the insulation may or the points may have burnt too wide a gap for the spark to still, one of the points may have

sss...

broken off. Either renew the plug, or clean it, reset the gap, and then test it. 16 Check the HT lead from the distributor to the plug. If the insulation is cracked or perished, renew the lead. Check the connections at the distributor cap. 17 Examine the distributor cap carefully for tracking. This can be recognised by a very thin black line running between two or more electrodes, or between an electrode and some other part of the distributor. These lines are paths which now conduct electricity across the cap, thus letting it run to earth. The only answer in this case is a new distributor cap. 18 Apart from the ignition timing being incorrect, other causes of misfiring have already been dealt with under the paragraphs

dealing with the failure of the engine to start. To recap, these are that:

(a) The coil may be faulty giving an intermittent misfire (b) There may be a damaged wire or loose connection in the low tension circuit (c) The condenser may be short-circuiting (where applicable) (d) There may be a mechanical fault in the distributor (broken driving spindle or contact breaker spring where applicable) 19 If the ignition timing is too far retarded it should be noted that the engine will tend to overheat, and there will be a quite noticeable

drop in power. If the engine is overheating and the power is down, and the ignition timing is correct, then the carburettor should be checked as it is likely that this is where the fault lies.

FLYWHEEL

FRICTION DISC

Unlike the clutch on most engines, the clutch pressure plate is bolted to the crankshaft flange and the flywheel, which is dish shaped, is bolted to the pressure plate with the friction disc being held between ‘them. This is in effect the reverse of the more conventional arrangement where the flywheel is bolted to the crankshaft flange and the clutch pressure plate bolted to the flywheel. The release mechanism consists of a metal disc, called the release plate, which is clamped in the centre of the pressure plate by

5e2 Clutch in turn pushes the centre of the release plate

inwards towards the crankshaft. The outer edge of the release plate presses on the pressure plate fingers forcing them back towards the engine and removing the pressure plate friction face from the friction disc, thus disconnecting the drive. When the clutch pedal is released the pressure plate reasserts itself, clamping the friction disc firmly against the flywheel and restoring the

drive. As the friction linings on the disc wear, the pressure plate will gradually move closer to the flywheel

1 The clutch adjustment should be checked at the intervals given in Routine Maintenance.

If it is clean and free from scoring there is no reason to remove it unless the friction disc shows signs of oil contamination. 3 If the plate surface is defective then it must be removed. Note exactly where the ends of the retaining ring are located (the ring must be refitted this way later), and prise the ring out with a screwdriver. The release plate may now be removed (photo). The pressure plate is held to the crankshaft flange by six bolts fitted using a thread locking compound. These will be difficult to remove as they were tightened to a high torque before the locking fluid set, so the plate must be held with a clamp similar to that shown in Fig. 5.5 (photo).

across the friction surface and measure any bow or taper with feeler gauges. 4 The rivets which hold the spring fingers in position must be tight. If any of them are loose the pressure plate must be scrapped. Finally, the condition of the friction surface. Ridges or scoring indicate undue wear and unless they can be removed by light application of emery paper it would be better to renew the plate. 5 The flywheel friction surface must be similarly checked. 6 So far the inspection has been for normal wear. Two other types of damage may be encountered. The first is overheating due to clutch slip. In extreme cases the pressure plate and flywheel may have radial cracks. Such faults mean that they require renewal. The second problem is contamination by oil or grease. This will cause clutch slip but probably without the cracks. There will be shiny black patches on the friction disc which will have a glazed surface. There is no cure for this, a new friction disc is required. In addition it is imperative that the source of contamination be located and rectified. It will be either the crankshaft oil seal or the gearbox input shaft oil seal (or bothl). Examine them and renew them as necessary the procedures are given in Chapters 1 and 6. 7 Whilst the gearbox is removed, it is as well to check the release bearing for satisfactory condition - see Section 7.

Fig. 5.8 Using VW tool 547 to centre the clutch friction disc (Sec 5) 4 Refitting is a reversal of removal; use thread locking compound on the bolts securing the plate to the crankshaft flange if they have been removed, and tighten them to the specified torque (photo). Make sure that the retaining ring is correctly seated (Figs. 5.6 and 5.7). Take care that no oil or grease is allowed to get onto the pressure plate or friction surfaces. 5 When refitting the clutch disc make sure the greater projecting boss which incorporates the torsion springs is furthest from the engine, then fit the flywheel over the pressure plate. Fit the securing bolts and tighten them finger tight only. 6 The next operation is to centre the clutch disc. If this is not done accurately the gearbox mainshaft will not be able to locate in the splines of the clutch disc hub, and it will be impossible to fit the gearbox. The best centralising tool is VW 547 which fits in the flywheel and has a spigot which fits exactly in

Clutch assembly - inspection

WHY 1 The most probable part of the clutch to require attention is the friction disc. Normal wear will eventually reduce its thickness. The lining must stand proud of the rivets by not less than 0.6 mm (0.025 in). At this measurement the lining is at the end of its life and a new friction plate is needed. 2 The friction disc should be checked for runout if possible. Mount the disc between the centres of a lathe and measure the run-out at the specified dimension from the outer edge, then compare the result with the Specifications. However, this requires a dial gauge and a mandrel. If the clutch has not shown signs of dragging then this test may be passed over, but if it has we suggest that expert help be sought to test the run-out (Fig. 5.10). 3 Examine the pressure plate. There are three important things to check. Put a straight-edge

1 The clutch release mechanism is located in the gearbox end housing and is accessible after the removal of the end cover or plate (as applicable). 2 On 4-speed gearbox models, unbolt the end cover from the gearbox and remove the gasket (photo). 3 On 5-speed gearbox models, first support the engine/gearbox unit with a trolley jack, then remove the torque strut and rear gearbox mounting and lower the jack a few inches. Using a sharp instrument, pierce the endplate and lever it out from the gearbox. A new plate must be obtained. 4 On both 4 and 5-speed gearboxes the release lever is located on the shaft by one circlip (early models) or two circlips (later models). Extract the circlip(s) (photo). 5 With the clutch cable disconnected (see Section 3) withdraw the release arm and shaft from the gearbox and remove the lever and spring (photo). 6 Remove the release bearing (photo) and on 4-speed models only, extract the guide sleeve. Removal of the pushrod on the 4speed gearbox is not possible unless the unit is lowered. 7 Rotate the release bearing and check it for ‘wear and roughness; renew it if necessary.

General description

The braking system is of four wheel hydraulic dual circuit type, with discs at the front and drum brakes at the rear. The dual circuit system is of the diagonal type so that with the failure of one hydraulic circuit, one front and one rear brake remain operative. A direct-acting brake servo unit is fitted to most models. The handbrake operates the rear brakes by cable, and on most models a warning light is provided on the instrument panel for the handbrake and low fluid level. Note that the Kelsey-Hayes type caliper may also be referred to as the Mk 2 type caliper.

2

thickness of the rear brake shoe linings should also be checked and renewed, if necessary. Where applicable the rear brake shoes should be adjusted. 4 Inspect the hydraulic pipes and unions for chafing, leakage, cracks and corrosion and also check the condition of the brake servo vacuum hose. 5 At the less frequent intervals given, renew the brake fluid in the hydraulic system.

Routine maintenance

1 The brake fluid level should be checked every week and, if necessary, topped-up with the specified fluid to the maximum level mark (photo). The reservoir is translucent and the check can be made without removing the filler cap. Any fall in level should be investigated. 2 At the intervals given in Routine Maintenance at the beginning of this manual the front brake pad thickness should be checked and all four pads renewed if any one is below the specified minimum thickness. 3 At the specified service intervals the

3 Remove the rubber plug from the adjuster hole in the backplate. Using a screwdriver, lever the adjuster wheel, teeth downwards (handle of the screwdriver upwards) until the lining binds in the drum (photo). Now back off the adjuster until the roadwheel will rotate without the drum touching the shoes. 4 Refit the rubber plug then adjust the opposite wheel in the same way.

Using a suitable drift tap out the pins securing the disc pads (photo). On some cars there may be a wire securing clip fitted round these pins (photo). This should be pulled off. If there is no clip the pins will have sleeves. 4 Remove the spreader and pull out the inner, direct pad (photos). If you are going to put the pads back then they must be marked so that they go back in the same place. Use a piece

of wire with a hook on the end to pull the pad out. Now lever the caliper over so that there is space between the disc and the outer pad, ease the pad away from the caliper onto the disc and lift it out. 5 Clean out the pad holder and check that the rubber dust cover is not damaged. Insert the outer pad and fit it over the projection on the caliper (photo). It will be necessary to push the piston in to insert the inner pad. This may cause the header tank to overflow unless action is taken to prevent it. Either draw some fluid out of the tank with a pipette or slacken the, bleed screw. We prefer the first method, but do not suck the fluid out with a syphon. It is poisonous. Use a pipette that has been

used for brake fluid only, not the battery hydrometer.

6 Push the piston in and check that the angle of the edges of the raised face of the piston is 20° to the face of the caliper (photo). Make a gauge out of cardboard as shown in the photo. If the angle is more or less, turn the piston until the angle is correct. 7 Insert the inner pad, fit the spreader and install the pins. Fit a new locking wire if the type of pin requires it. 8 Do not forget to shut the bleed screw (if it was opened) as soon as the piston has been forced back. We do not like this method because there is a chance of air entering the cylinder and we do not like spare brake fluid about on the caliper while working on the friction pads. 9 Work the footbrake a few times to settle the pistons. Now repeat the job for the other wheel. 10 Refit the roadwheels, lower to the ground and take the car for a test run.

MOT Test Checks rere1 This is a guide to getting your vehicle through the MOT test. Obviously it will not be possible to examine the vehicle to the same Standard as the professional MOT tester. However, working through the following checks will enable you to identify any problem areas before submitting the vehicle for the test. Where a testable component is in borderline condition, the tester has discretion in deciding whether to pass or fail it. The basis of such discretion is whether the tester would be happy for a close relative or friend to use the vehicle with the component in that condition. If the vehicle presented is clean and evidently well cared for, the tester may be more inclined to pass a borderline component than if the vehicle is scruffy and apparently neglected. It has only been possible to summarise the test requirements here,

based on the regulations in force at the time of printing. Test standards are becoming increasingly stringent, although there are some exemptions for older vehicles. For full details obtain a copy of the Haynes publication Pass the MOT! (available from stockists of Haynes manuals). An assistant will be needed to help carry out some of these checks. The checks have been sub-divided into four categories, as follows:

Check for excessive free play between the steering wheel and the steering gear, indicating wear or insecurity of the steering column joints, the column-to-steering gear coupling, or the steering gear itself. L] Have your assistant turn the steering wheel more vigorously in each direction, so that the roadwheels just begin to turn. As this is done, examine

all the

Check for free play or insecurity at the wheel bearings, suspension balljoints, or suspension mountings, pivots and attachments. L] Now grasp the wheel at the 12 o’clock and

6 o’clock positions and repeat the previous inspection. Spin the wheel, and check for roughness or tightness of the front wheel bearing.

L] The same general checks apply to vehicles fitted with other suspension types, such as torsion bars, hydraulic displacer units, etc. Ensure that all mountings and attachments are secure, that there are no signs of excessive wear, corrosion or damage, and (on hydraulic types) that there are no fluid leaks or damaged pipes. L] Inspect the shock absorbers for signs of serious fluid leakage. Check for wear of the mounting bushes or attachments, or damage to the body of the unit.

Driveshafts (fwd vehicles only) L] Rotate each front wheel in turn and inspect the constant velocity joint gaiters for splits or damage. Also check that each driveshaft is straight and undamaged.

blue or clearly-visible

black smoke comes from the tailpipe for more than 5 seconds, the vehicle will fail. As a rule of thumb, blue smoke signifies oil being burnt (engine wear) while black smoke signifies unburnt fuel (dirty air cleaner element, or other carburettor or fuel system fault). (An exhaust gas analyser capable of (CO) and carbon monoxide measuring hydrocarbons (HC) is now needed. If such an instrument cannot be hired or borrowed, a local garage may agree to perform the check for a small fee.

CO emissions (mixture) LU At the time of writing, the maximum CO level at idle is 3.5% for vehicles first used after August 1986 and 4.5% for older vehicles. From January 1996 a much tighter limit (around 0.5%) applies to catalyst-equipped vehicles first used from August 1992. If the CO level cannot be reduced far enough to pass the test (and the fuel and ignition systems are otherwise in good condition) then the carburettor is badly worn, or there is some problem in the fuel injection system or catalytic converter (as applicable).

HC emissions LJ With the CO emissions within limits, HC emissions must be no more than 1200 ppm (parts per million). If the vehicle fails this test at idle, it can be re-tested at around 2000 rpm; if the HC level is then 1200 ppm or less, this

counts as a pass. L] Excessive HC emissions can be caused by oil being burnt, but they are more likely to be due to unburnt fuel.

L] Have the engine at normal operating temperature, and make sure that it is in good tune (ignition system in good order, air filter element clean, etc).

_] Before any measurements are carried out, raise the engine speed to around 2500 rpm, and hold it at this speed for 20 seconds. Allow

Diesel models LJ The only emission test applicable to Diesel engines is the measuring of exhaust smoke density. The test involves accelerating the engine several times to its maximum unloaded speed.

Note: /t is of the utmost importance that the engine timing belt is in good condition before the test is carried out. _] Excessive smoke can be caused by a dirty air cleaner element. Otherwise, professional advice may be needed to find the cause.

Tools and Working Facilities rerss

Introduction A selection of good tools is a fundamental requirement for anyone contemplating the maintenance and repair of a motor vehicle. For the owner who does not possess any, their purchase will prove a considerable expense, offsetting some of the savings made by doing-it-yourself. However, provided that the tools purchased meet the relevant national safety standards and are of good quality, they will last for many years and prove an extremely worthwhile investment. To help the average owner to decide which tools are needed to carry out the various tasks detailed in this manual, we have compiled three lists of tools under the following headings: Maintenance and minor repair, Repair and overhaul, and Special. Newcomers to practical mechanics should start off with the Maintenance and minor repair tool kit, and confine themselves to the simpler jobs around the vehicle. Then, as confidence and experience grow, more difficult tasks can be undertaken, with extra

tools being purchased as, needed. In this way, a minor repair tool kit can Repair and overhaul considerable period of major cash outlays. The yourselfer will have a tool

and when, they are Maintenance and be built up into a tool kit over a time, without any experienced do-itkit good enough for

most repair and overhaul procedures, and will

add tools from the Special category when it is felt that the expense is justified by the amount of use to which these tools will be put.

Repair and overhaul tool kit These tools are virtually essential for anyone undertaking any major repairs to a motor vehicle, and are additional to those given in the Maintenance and minor repair list. Included in this list is a comprehensive set of sockets. Although these are expensive, they will be found invaluable as they are so versatile - particularly if various drives are included in the set.

The tools in this list are those which are not used regularly, are expensive to buy, or which need to be used in accordance with their manufacturers’ instructions. Unless relatively difficult mechanical jobs are undertaken frequently, it will not be economic to buy many of these tools. Where this is the case, you could consider clubbing together with friends (or joining a motorists’ club) to make a joint purchase, or borrowing the tools against a deposit from a local garage or tool hire specialist. It is worth noting that many of the larger DIY superstores now carry a large range of special tools for hire at modest rates. The following list contains only those tools and instruments freely available to the public, and not those special tools produced by the vehicle manufacturer specifically for its dealer network. You will find occasional references to these manufacturers’ special tools in the text of this manual. Generally, an alternative method of doing the job without the vehicle

Buying tools For practically all tools, a tool factor is the best source, since he will have a very comprehensive range compared with the average garage or accessory shop. Having said that, accessory shops often offer excellent quality tools at discount prices, so it pays to shop around. Remember, you don’t have to buy the most expensive items on the shelf, but it is always advisable to steer clear of the very cheap tools. There are plenty of good tools around at

t se on ti la al st in l/ va mo re g in ar be d an Bush

reasonable prices, but always purchase items which meet the

aim to relevant

national safety standards. If in doubt, ask the proprietor or manager of the shop for advice

before making a purchase.

Care and maintenance of tools Having purchased a reasonable tool kit, it is necessary to keep the tools in a clean and serviceable condition. After use, always wipe off any dirt, grease and metal particles using a clean, dry cloth, before putting the tools away. Never leave them lying around after they have been used. A simple tool rack on the garage as wall for items such or workshop screwdrivers and pliers is a good idea. Store all normal spanners and sockets in a metal box. Any measuring instruments, gauges, meters, etc, must be carefully stored where they cannot be damaged or become rusty. Take a little care when tools are used. Hammer heads inevitably become marked, and screwdrivers lose the keen edge on their blades from time to time. A little timely attention with emery cloth or a file will soon restore items like this to a good serviceable finish.

Working facilities Not to be forgotten when discussing tools

Stud extractor set

is the workshop itself. If anything more than routine maintenance is to be carried out, some form of suitable working area becomes essential. It is appreciated that many an ownermechanic is forced by circumstances to remove an engine or similar item without the benefit of a garage or workshop. Having done this, any repairs should always be done under the cover of a roof.

Wherever possible, any dismantling should be done on a clean, flat workbench or table at a suitable working height. Any workbench needs a vice; one with a jaw opening of 100 mm is suitable for most jobs. As mentioned previously, some clean dry storage space is also required for tools, as well as for any lubricants, cleaning fluids, touch-up paints and so on, which become necessary. Another item which may be required, and which has a much more general usage, is an electric drill with a chuck capacity of at least 8 mm. This, together with a good range of twist drills, is virtually essential for fitting accessories. Last, but not least, always keep a supply of old newspapers and clean, lint-free rags available, and try to keep any working area as clean as possible.

reres General Repair Procedures Whenever servicing, repair or overhaul work is carried out on the car or its components, and procedures the following observe

instructions. This will assist in carrying out the operation efficiently and to a professional standard of workmanship.

Joint mating faces and gaskets When separating components at their mating faces, never insert screwdrivers or similar implements into the joint between the faces in order to prise them apart. This can cause severe damage which results in oil leaks, coolant Separation is along the joint order to break

leaks, etc upon reassembly. usually achieved by tapping with a soft-faced hammer in the seal. However, note that

this method may not be suitable where dowels are used for component location. Where a gasket is used between the mating faces of two components, a new one must be fitted on reassembly; fit it dry unless otherwise stated in the repair procedure. Make sure that the mating faces are clean and dry, with all traces of old gasket removed. When cleaning a

joint face, use a tool which is unlikely to score or damage the face, and remove any burrs or nicks with an oilstone or fine file. Make sure that tapped holes are cleaned with a pipe cleaner, and keep them free of jointing compound, if this is being used, unless specifically instructed otherwise. Ensure that all orifices, channels or pipes are clear, and blow through them, preferably using compressed air.

Oil seals Oil seals can be removed by levering them out with a wide flat-bladed screwdriver or similar implement. Alternatively, a number of self-tapping screws may be screwed into the seal, and these used as a purchase for pliers or some similar device in order to pull the seal free. Whenever an oil seal is removed from its working location, either individually or as part of an assembly, it should be renewed. The very fine sealing lip of the seal is easily damaged, and will not seal if the surface it contacts is not completely clean and free from scratches, nicks or grooves. If the original sealing surface of the component cannot be restored, and the manufacturer has not made provision for slight relocation of the seal relative to the sealing surface, the component should be renewed. Protect the lips of the seal from any surface which may damage them in the course of fitting. Use tape or a conical sleeve where possible. Lubricate the seal lips with oil before fitting and, on dual-lipped seals, fill the space between the lips with grease. Unless otherwise stated, oil seals must be fitted with their sealing lips toward the lubricant to be sealed. Use a tubular drift or block of wood of the

unshouldered, the seal should be fitted with

its face flush with the housing top face (unless otherwise instructed).

Screw threads and fastenings Seized nuts, bolts and screws are quite a

common occurrence where corrosion has set in, and the use of penetrating oil or releasing fluid will often overcome this problem if the offending item is soaked for a while before attempting to release it. The use of an impact driver may also provide a means of releasing such stubborn fastening devices, when used appropriate the with conjunction in screwdriver bit or socket. If none of these methods works, it may be necessary to resort to the careful application of heat, or the use of a hacksaw or nut splitter device. Studs are usually removed by locking two nuts together on the threaded part, and then using a spanner on the lower nut to unscrew the stud. Studs or bolts which have broken off below the surface of the component in which they are mounted can sometimes be removed using a stud extractor. Always ensure that a blind tapped hole is completely free from oil, grease, water or other fluid before installing the bolt or stud. Failure to do this could cause

the housing to crack due to the hydraulic action of the bolt or stud as it is screwed in. When tightening a castellated nut to accept a split pin, tighten the nut to the specified torque, where applicable, and then tighten further to the next split pin hole. Never slacken the nut to align the split pin hole, unless stated in the repair procedure. When checking or retightening a nut or bolt to a specified torque setting, slacken the nut or bolt by a quarter of a turn, and then retighten to the specified setting. However, this should not be attempted where angular tightening has been used. For some screw fastenings, notably cylinder head bolts or nuts, torque wrench settings are no longer specified for the latter stages of tightening, “angle-tightening” being called up instead. Typically, a fairly low torque wrench setting will be applied to the bolts/nuts in the correct sequence, followed by one or more stages of tightening through specified angles.

Locknuts, locktabs and washers

Any fastening which will rotate against a component or housing during tightening should always have a washer between it and the relevant component or housing. Spring or split washers should always be renewed when they are used to lock a critical component such as a _ big-end bearing retaining bolt or nut. Locktabs which are folded over to retain a nut or bolt should always be renewed. Self-locking nuts can be re-used in noncritical areas, providing resistance can be felt when the locking portion passes over the bolt

Special tools Some repair procedures in this manual entail the use of special tools such as a press, two or three-legged pullers, spring compressors, etc. Wherever possible, suitable readily-available alternatives to the manufacturer’s special tools are described, and are shown in use. In some instances, where no

alternative is possible, it has been necessary to resort to the use of a manufacturer's tool, and this has been done for reasons of safety as well as the efficient completion of the repair operation. Unless you are highly-skilled and have a thorough understanding of the procedures described, never attempt to bypass the use of any special tool when the procedure described specifies its use. Not only is there a very great risk of personal injury, but expensive damage could be caused to the components involved.

Environmental considerations When

disposing of used engine oil, brake

fluid, antifreeze, etc, give due consideration to

any detrimental environmental effects. Do not, for instance, pour any of the above liquids down drains into the general sewage system, or onto the ground to soak away. Many local council refuse tips provide a facility for waste oil disposal, as do some garages. If none of these facilities are available, consult your local Environmental Health Department, or the National Rivers Authority, for further advice.

With the universal tightening-up of legislation regarding the emission of environmentally-harmful substances from motor vehicles, most vehicles have tamperproof devices fitted to the main adjustment points of the fuel system. These devices are primarily designed to prevent unqualified persons from adjusting the fuel/air mixture, with the chance of a consequent increase in toxic emissions. If such devices are found during servicing or

overhaul, they should, wherever possible, be renewed or refitted in accordance with the manufacturer’s requirements or current legislation.

Note: Itis antisocial and illegal to dump oil down the drain. To find the location of your local oil

recycling bank, call this number free.

Buying spare parts & Vehicle identification numbers rerss

Buying spare parts Spare parts are available from many sources, for example: VW garages, other garages and accessory shops, and motor factors. Our advice regarding spare part sources is as follows: Officially appointed VW garages - This is the best source of parts which are peculiar to your vehicle and are otherwise not generally available (eg complete cylinder heads, internal gearbox components, badges, interior trim, etc). It is also the only place at which you should buy parts if your car is still under

warranty - non-VW components may invalidate the warranty. To be sure of obtaining the correct parts it will always be necessary to give the storeman your car’s engine and chassis number, and if possible. to take the ‘old’ part along for positive identification. Remember that many parts are available on a factory exchange scheme - any parts returned

should

always

be clean!

It

obviously makes good sense to go straight to to the specialists on your car for this type of

etc). Motor factors will often provide new or reconditioned components on a_ part exchange basis - this can save a considerable amount of money.

Vehicle identification

numbers It is most important to identify the vehicle accurately when ordering spare parts or asking for information. There have been many modifications to this range already. The vehicle identification plate is on top of the frame by the radiator (photo). The chassis number is on the top of the right-hand front suspension strut housing. The engine number is on the cylinder block by the distributor (photo). The transmission code is stamped on the top of the flange where the transmission joins the engine. These numbers should be identified and

recorded by the owner; they are required when ordering spares, going through the customs, and regrettably, by the police, if the

vehicle is stolen. When ordering spares remember that VW output is such that inevitably spares vary, are duplicated. and are held on a usage basis. If the storeman does not have the correct identification, he cannot produce the correct item. It is a good idea to take the old part if possible to compare it with a new one. The storeman

has many customers to satisfy, so

be accurate and patient. In some cases, particularly in the brake system, more than one manufacturer supplies an assembly, eg both Teves and Girling supply front calipers. The assemblies may be interchangeable but the integral parts are not. This is only one of the pitfalls in the buying of spares, so be careful to make an ally of the storeman. When fitting accessories it is best to fit VW ones. They are designed recommended specifically for the vehicle.

part for they are best equipped to supply you. Other garages and accessory shops - These are often very good places to buy materials

and components needed for the maintenance of your car (eg oil filters, spark plugs, bulbs,

reFeio Fault Finding

Introduction The vehicle owner who does his or her own maintenance according to the recommended schedules should not have to use this section of the manual very often. Modern component reliability is such that, provided those items subject to wear or deterioration are inspected or renewed at the specified intervals, sudden failure is comparatively rare. Faults do not usually just happen as a result of sudden failure, but develop over a period of time. Major mechanical failures in particular are usually preceded by characteristic symptoms over hundreds or even thousands of miles. Those components which do occasionally fail without warning are often small and easily carried in the vehicle. With any fault finding, the first step is to decide where to begin investigations. Sometimes this is obvious, but on other occasions a little detective work will be necessary. The owner who makes half a or adjustments haphazard dozen replacements may be successful in curing a fault (or its symptoms), but he will be none the wiser if the fault recurs and he may well have spent more time and money than was necessary. A calm and logical approach will be found to be more satisfactory in the long run. Always take into account any warning signs or abnormalities that may have been noticed in the period preceding the fault — power loss, high or low gauge readings, unusual noises or smells, etc - and remember that failure of components such as fuses or spark plugs may only be pointers to some underlying fault.

The pages which follow here are intended to help in cases of failure to start or breakdown on the road. There is also a Fault Diagnosis Section at the end of each Chapter which should be consulted if the preliminary checks prove unfruitful. Whatever the fault, certain basic principles apply. These are as follows: Verify the fault. This is simply a matter of being sure that you know what the symptoms are before starting work. This is particularly important if you are investigating a fault for someone else who may not have described it very accurately. Don’t overlook the obvious. For example, if the vehicle won’t start, is there petrol in the tank? (Don’t take anyone else’s word on this particular point, and don’t trust the fuel gauge either!) If an electrical fault is indicated, look for loose or broken wires before digging out the test gear. Cure the disease, not the symptom.

Substituting a flat battery with a fully charged one will get you off the hard shoulder, but if the underlying cause is not attended to,the

new battery will go the same way. Similarly, changing oil-fouled spark plugs for a new set will get you moving again, but remember that the reason for the fouling (if it wasn’t simply an incorrect grade of plug) will have to be established and corrected. Don’t take anything for granted.

Particularly,

don’t

forget

that

a

‘new’

component may itself be defective (especially

if it’s been

rattling round

in the boot for

months), and don’t leave components out of a fault diagnosis sequence just because they

are new or recently fitted. When you do finally diagnose a difficult fault, you'll probably realise that all the evidence was there from the start.

Electrical faults Electrical faults can be more puzzling than straightforward mechanical failures, but they are no less susceptible to logical analysis if the basic principles of operation are understood. Vehicle electrical wiring exists in extremely

unfavourable

conditions —

heat,

vibration and chemical attack and the first things to look for are loose or corroded connections and broken or chafed wires, especially where the wires pass through holes in the bodywork or are subject to vibration. All metal-bodied vehicles in current production have one pole of the battery ‘earthed’, ie connected to the vehicle bodywork, and in nearly all modern vehicles it is the negative (-) terminal. The various electrical components — motors, bulb holders, etc — are also connected to earth, either by means of a lead or directly by their mountings. Electric current flows through the component and then back to the battery via the bodywork. If the component mounting is loose or corroded, or if a good path back to the battery is not available, the circuit will be incomplete and malfunction will result. The engine and/or

gearbox are also earthed by means of flexible metal straps to the body or subframe; if these straps are loose or missing, starter motor, generator and ignition trouble may result. Assuming the earth return to be satisfactory, electrical faults will be due either

Fault Finding rere11 to component malfunction or to defects in the Current supply. Individual components are dealt with in Chapter 9. If supply wires are broken or cracked internally this results in an open-circuit, and the easiest way to check for this is to bypass the suspect wire temporarily with a length of wire having a crocodile clip or suitable connector at each end. Alternatively, a 12V test lamp can be used to verify the presence of supply voltage at various points along the wire and the break can be thus isolated. If a bare portion of a live wire touches the bodywork or other earthed metal part, the electricity will take the low-resistance path thus formed back to the battery: this is known ~ as a short-circuit. Hopefully a short-circuit will blow a fuse, but otherwise it may cause burning of the insulation (and possibly further short-circuits) or even a fire. This is why it is inadvisable to bypass persistently blowing fuses with silver foil or wire.
