# DO NOT REUSE HEAD BOLTS (INFORMATIONAL)

#### SUBJECT: DO NOT REUSE HEADBOLTS (INFORMATIONAL)

#### VEHICLES AFFECTED: 1985-92 M-CAR (SPRINT/METRO) AND 1989-92 J-TRUCK (TRACKER)

The headbolts on 1985-92 m car (Sprint/Metro) and 1989-92 i truck (Tracker) may elongate while in use, which is normal with aluminum cylinder heads. While this will not cause any operational problems with the vehicle, the bolts should not be reused if the headbolts are removed for any reason. New bolts should always be used. Follow Service Manual instructions for proper torquing procedures.

There are two head bolts used for these vehicles, Part Numbers #96061591 and #96059992. They are different lengths, and are not interchangeable. Consult the Parts Book for the proper application.

Parts are currently available from CANSPO.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
