‘Abo thisut manual Its purpose The purpose of this manual is to help you get the best value from your vehicle. It _ can do so in several ways. It can help you _ decide what work must be done, even if you choose to have it done by a dealer service department or a repair shop; it provides information and procedures for routine maintenance and servicing; and it offers diagnostic _ and repair procedures to follow when trouble occurs. We hope you use the manual to tackle _ the work yourself. For many simpler jobs, doing it yourself may be quicker than arranging an appointment to get the vehicle into a _ shop and making the trips to leave it and pick it up. More importantly, a lot of money can be saved by avoiding the expense the shop

must pass on to you to cover its labor and overhead costs. An added benefit is the sense of satisfaction and accomplishment that you feel after doing the job yourself.

Using the manual The manual is divided into Chapters. Each Chapter is divided into numbered Sections, which are headed in bold type between horizontal lines. Each Section consists of consecutively numbered paragraphs. At the beginning of each numbered Section you will be referred to any illustrations which apply to the procedures in that Section. The reference numbers used in illustration captions pinpoint the pertinent Section and the Step within that Section. That is, illustration 3.2 means the illustration refers to Section 3 and Step (or paragraph) 2 within

that Section. Procedures, once described in the text, are not normally repeated. When it’s necessary to refer to another Chapter, the reference will be given as Chapter and Section number. Cross references given without use of the word “Chapter” apply to Sections and/or paragraphs in the same Chapter. For example, “see Section 8” means in the same Chapter. References to the left or right side of the vehicle assume you are sitting in the driver’s seat, facing forward. Even though we have prepared this manual with extreme care, neither the publisher nor the author can accept responsibility for any errors in, or omissions from, the information given.

NOTE A Note provides information necessary to properly complete a procedure or information which will make the procedure easier to understand.

CAUTION A Caution provides a special procedure or special steps which must be taken while completing the procedure where the Caution is found. Not heeding a Caution can result in damage to the assembly being worked on.

WARNING A Warning provides a special procedure or special steps which must be taken while completing the

procedure where the Warning is found. Not heeding a Warning can result in personal injury.

Introduction to the Buick, Oldsmobile and Pontiac full-size, front-wheel drive models The full-size General Motors models covered by this manual are front engine/front-wheel drive “C” and “H” body vehicles only. Most are four-door sedans,

although some two-door models are available.

All models are powered by a transversely mounted V6 engine which drives the front wheels through an automatic transaxle and independent driveaxles. Independent suspension, featuring coil springs and struts or shock absorbers, is

used at all four wheels. The rack and pinion steering unit is mounted behind the engine. The brakes are disc at the front and drums or discs at the rear, with power assist

standard.

Vehicle identification numbers Modifications are a continuing and unpublicized part of vehicle manufacturing. Since spare parts manuals and lists are compiled on a numerical basis, the individual vehicle numbers are essential to correctly identify the component required.

cation statement.

Body identification plate

Vehicle Identification Number

(VIN) This very important identification number is stamped on a plate attached to the left side of the dashboard and is visible through the driver’s side of the windshield (see illustration). The VIN also appears on the Vehicle Certificate of Title and Registration. It contains information such as where and when the vehicle was manufactured, the model year and the body style.

Vehicle Certification Plate The Vehicle Certification Plate (VC label) is affixed to the rear of the left front door. The

The body identification plate is located in the engine compartment on the upper surface of the radiator support. Like the VIN, it contains valuable information concerning the production of the vehicle, as well as information on the options with which it is equipped. This plate is especially useful for matching the color and type of paint for repair work.

Transaxle identification number The transaxle identification number is located on the right rear side of the transaxle (see illustration).

Engine identification number

Vehicle Emissions Control Information label

The engine ID number is located on a pad at the drivebelt (right) end of the engine block, adjacent to the water pump or on the front surface of the block at the transaxle (left) end, adjacent to the starter (see illustration).

The Vehicle Emissions Control Information label is under the hood, often attached to the left shock tower (see Chapter 6 for more information and an illustration of the label).

Buying parts Replacement parts are available from many sources, which generally fall into one of two categories - authorized dealer parts departments and independent retail auto parts stores. Our advice concerning these parts is as follows: Retail auto parts stores: Good auto parts stores will stock frequently needed components which wear out relatively fast, such as clutch components, exhaust systems, brake parts, tune-up parts, etc. These stores often supply new or reconditioned

parts on an exchange basis, which can save a considerable amount of money. Discount auto parts stores are often very good places to buy materials and parts needed for general vehicle maintenance such as oil, grease, filters, spark plugs, belts, touch-up paint, bulbs, etc. They also usually sell tools and general accessories, have convenient hours, charge lower prices and can often be found not far from home. Authorized dealer parts department: This is the best source for parts which are

unique to the vehicle and not generally available elsewhere (Such as major engine parts, transmission parts, trim pieces, etc.). Warranty information: lf the vehicle is still covered under warranty, be sure that any replacement parts purchased - regardless of the source - do not invalidate the warranty! To be sure of obtaining the correct parts, have engine and chassis numbers available and, if possible, take the old parts along for positive identification.

Maintenance techniques, tools and working facilities Maintenance techniques There are a number of techniques involved in maintenance and repair that will be referred to throughout this manual. Application of these techniques will enable the home mechanic to be more efficient, better organized and capable of performing the various tasks properly, which will ensure that the repair job is thorough and complete.

Fasteners Fasteners are nuts, bolts, studs and screws used to hold two or more parts together. There are a few things to keep in mind when working with fasteners. Almost all of them use a locking device of some type, either a lockwasher, locknut, locking tab or thread adhesive. Ail threaded fasteners

Grade 1 or 2

Grade 8

should be clean and straight, with undamaged threads and undamaged corners on the hex head where the wrench fits. Develop the habit of replacing all damaged nuts and bolts with new ones. Special locknuts with nylon or fiber inserts can only be used once. If they are removed, they lose their locking ability and must be replaced with new ones. Rusted nuts and bolts should be treated with a penetrating fluid to ease removal and prevent breakage. Some mechanics use turpentine in a spout-type oil can, which works quite well. After applying the rust. penetrant, let it work for a few minutes before trying to loosen the nut or bolt. Badly rusted fasteners may have to be chiseled or sawed off or removed with a special nut breaker, available at tool stores. If a bolt or stud breaks off in an assembly, it can be drilled and removed with a special tool commonly available for this purpose. Most automotive machine shops can perform

Fastener sizes For a number of reasons, automobile manufacturers are making wider and wider use of metric fasteners. Therefore, it is important to be able to tell the difference between

standard (sometimes called U.S. or SAE) and

metric hardware, since they cannot be inter-

changed. All bolts, whether standard or metric, are sized according to diameter, thread pitch and

N/a

length. For example, a standard 1/2 - 13 x 1

sraceseanc vesntSy cuurs aaa anes cavemen aCe

bolt is 1/2 inch in diameter, has 13 threads per

inch and is 1 inch long. An M12 - 1.75 x 25 metric bolt is 12 mm in diameter, has a thread

pitch of 1.75 mm (the distance between threads) and is 25 mm long. The two bolts are nearly identical, and easily confused, but they are not interchangeable. In addition to the differences in diameter, thread pitch and length, metric and standard bolts can also be distinguished by examining the bolt heads. To begin with, the distance across the flats on a standard bolt head is measured in inches, while the same dimension on a metric bolt is sized in millimeters (the same is true for nuts). As a result, a standard wrench should not be used on a metric bolt and a metric wrench should not be used on a standard bolt. Also, most standard bolts have slashes radiating out from the center of the head to denote the grade or strength of the bolt, which is an indication of the amount of torque that can be applied to it. The greater the number of slashes, the greater the strength of the bolt. Grades 0 through 5 are commonly used on automobiles. Metric bolts have a property class (grade) number, rather than a slash, molded into their heads to indicate bolt strength. In this case, the higher the number, the stronger the bolt. Property class numbers 8.8, 9.8 and 10.9 are commonly used on automobiles. Strength markings can also be used to distinguish standard hex nuts from metric hex nuts. Many standard nuts have dots stamped into one side, while metric nuts are marked with a number. The greater the number of dots, or the higher the number,

the

greater the strength of the nut. Metric studs are also marked on their ends according to property class (grade). Larger studs are numbered (the same as metric bolts), while smaller studs carry a geometric code to denote grade. It should be noted that many fasteners, especially Grades 0 through 2, have no distinguishing marks on them. When such is the case, the only way to determine whether it is standard or metric is to measure the thread pitch or compare it to a Known fastener of the same size. Standard fasteners are often referred to as SAE, as opposed

to metric.

Common

spark plug conditions NORMAL Symptoms: Brown to grayish-tan color and slight electrode wear. Correct heat range for engine and operating conditions. Recommendation: When new spark plugs are installed, replace with plugs of the same heat range.

TOO HOT

WORN Symptoms: Rounded electrodes with a small amount of deposits on

tne firing end. Normal color. Causes hard starting in damp or cold weather and poor fuel economy. Recommendation: Plugs have been left in the engine too long. Replace with new plugs of the same heat range. Follow the recommended maintenance schedule.

ASH DEPOSITS

HIGH SPEED GLAZING

Symptonis: Light brown deposits encrusted on the side or center electrodes or both. Derived from oil and/or fuel additives. Excessive amounts may mask the spark, causing misfiring and hesitation during acceleration. Recommendation: |f excessive

Symptoms: Insulator has yellowish, glazed appearance. Indicates that combustion chamber temperatures have risen suddenly during hard acceleration. Normal deposits melt to form a conductive coating.

OIL DEPOSITS Symptoms: Oily coating caused by poor oil control. Oil is leaking past worn valve guides or piston rings into the combustion chamber. Causes hard starting, misfiring and hesitation. Recommendation: Correct the mechanical condition with necessary repairs and install new plugs.

Causes misfiring at high speeds. Recommendation: _ |nstall new plugs. Consider using a colder plug if driving habits warrant.

DETONATION Symptoms: Insulators may be cracked or chipped. Improper gap setting techniques can also result in a fractured insulator tip. Can lead to piston damage. Recommendation: Make sure the fuel anti-knock values meet engine requirements. Use care when setting the gaps on new plugs. Avoid lugging the engine.

MECHANICAL GAP BRIDGING Symptoms: Combustion deposits lodge between the electrodes. Heavy deposits accumulate and bridge the electrode gap. The plug ceases to fire, resulting in a dead cylinder, Recommendation: Locate the faulty plug and remove the deposits from between the electrodes.

DAMAGE

Symptoms: May be caused by a foreign object in the combustion chamber or the piston striking an incorrect reach (too long) plug. Causes a dead cylinder and could result in piston damage. Recommendation: Repair the mechanical damage. Remove the foreign object from the engine and/or plug.
