CAUTION To reduce the chance of personal injury and/or property damage, the following instructions must be carefully observed: Proper service and repair are important to the safety of the service technician and the safe, reliable operation of all motor vehicles. If part replacement is necessary, the part must be replaced with one of the same part number or with an equivalent part. Do not use a replacement part of lesser quality. The service procedures recommended and described inthis service manual are effective methods of performing service and repair. Some of these procedures require the use of tools specially design- ed for the purpose. Accordingly, anyone who intends t o use a replacement part, ser- vice procedure or tool, which is not recommended by the vehicle manufacturer, must first determine that neither his safety nor the safe operation of the vehicle will be jeopardized by the replace- ment part, service procedure or tool selected. It is important to note that this manual contains various 'Cautions' and 'Notices' that must be carefully observed in order to reducethe risk of personal injury during service or repair, or the possibility that improper service or repair may damage the vehicle or render it unsafe. It is also important to understand that these 'Cautions' and 'Notices' are not exhaustive, because it is impossible to warn of all the possible hazardous consequences that might result from fail- ure t o follow these instructions.

  • 4. OA-2 GENERAL INFORMATION VIN NUMBER PLATE LOCATION Fig. 2 Vehicle Identification Number Plate Location marking indicating the strength of the material in the fastener as outlined below. Metric cross recess screws are identified by a Posidriv or Type 1A cross recess as shown in Figure 8. Either a Phillips head or Type 1A cross recess screwdriver can be used in Posidriv recess screw heads, but Type 1A cross recess screwdrivers will perform better. NOTICE:Most metric fasteners have a blue color coating. However, this should not be used as a positive way of identifying as some metric fasteners are not color coated. General Motors Engineering Standards, along with other North American Industries, have adopted a portion of the standard metric fastener sizes defined by IS0 (International Standards Organization). This was done to reduce the number of fastener sizes used and yet retain the best strength qualities in each thread size. For example, the customary 1/4-20 and 1/4-28 screws are replaced by the metric M6.0 X 1 screw which has nearly the same diameter and 25.4 threads per inch. The thread pitch is in between the customary coarse and fine thread pitches. Metric and customary thread notation differ slightly. The difference is shown in Figure 9. FASTENER STRENGTH ODENTIFIGATION Most commonly used metric fastener strength property classes are 9.8 and 10.9 with the class identification embossed on the head of each bolt. Customary (inch) strength classes range from grade 2 to 8 with radial line identification embossed on each bolt head (i.e., grade 7 bolt will exhibit 5 embossed radial lines on the bolt head). Some metric nuts will be marked with single digit strength identification numbers on the nut face. Figure 12shows the different strength markings. When replacing metric fasteners,be careful to use bolts and nuts of the same strength or greater than the original fasteners (the same number marking or higher) .It is also important to select replacement fasteners of the correct size. Correct replacement bolts and nuts are available through the parts division. Many metric fasteners available in the after-market parts channels were designed to metric standards of countries other than the United States. These fasteners may be of a lower strength, differentthread pitch and may not have the numbered head marking system. The metric fasteners used on GM products are designed to new, international standards that may not be used by some nondomestic bolt and nut suppliers. In general, except for special applications, the common sizes and pitches are: M 6.0 X 1 M 8 x 1.25 M 10 X 1.5 M 12 X 1.75 M 1 4 x 2 I PREVAILINGTORQUE FASTENERS A prevailing torque nut is designed to develop an interference between the nut and bolt threads. This is most often accomplished by distortion of the top of an all-metal nut or by using a nylon patch on the threads in the middle of the hex flat. A nylon insert may also be used as a method of interference between nut and bolt threads (Fig. 11). A prevailing torque bolt is designed to develop an interference between bolt and nut threads, or the threads of a tapped hole. This is accomplished by distorting some of the threads or by using a nylon patch or adhesive (Fig. 11). RECOMMENDATIONS FOR FASTENER REUSE: I Clean, unrusted prevailing torque nuts and bolts may be reused as follows: a. Clean dirt and other foreign material off nut or bolt. b. Inspect nut or bolt to insure there are no cracks, elongation, or other signs of abuse or overtightening. (If there is any doubt, replace with a new prevailing torque fastener of equal or greater strength.) c. Lightly coat bolt & nut with engine oil. Assemble parts and hand start nut or bolt. d. Observe that before fastener seats, it develops torque per the chart in Figure 10. (If there is any doubt, replace with a new prevailing torque fastener of equal or greater strength.) e. Tighten fastener to torque specified in appropriate section of this manual. Bolts and nuts which are rusty or damaged should be replaced with new parts of equal or greater strength. VEHICLE LIF"TING PROCEDURES NOTICE: When jacking or lifting vehicle from frame side rails, be certain lift pads do not contact catalytic converter as damage to converter will result. Many dealer servicefacilities and service stations are equipped with a type of automotive hoist which must bear upon some part of the frame in order to lift the vehicle. Figures 14 and 15 indicate the recommended areas for hoist contact for Pontiac Sunbird models. If any other hoist methods are used, special care must be used not to damage the fuel tank, filler neck, I exhaust system or underbody. I
