SERVICE GUILD: A/C COMPRESSOR BOLT/STUD TORQUE LOSS (REPAIR

MODELS AFFECTED: 1987-88 SKYHAWKS WITH 2.OL L-4 OHC ENGINES (87 VIN CODES K, M; 88 VIN CODE K)

NOTICE: This bulletin is revised to correct a part number for Loctite(R) 242 material. Please discard Dealer Service Bulletin 88-1-6.

Any repair to the A/C compressor or the A/C belt system will require loosening some A/C bracket bolts. To prevent future torque loss after retightening of these bolts, a preferred repair method is recommended.

All the A/C compressor bolts use an adhesive patch for high initial torque retention. To maintain the high torque after any repair, the bolt or stud should be replaced with an appropriate new bolt or stud or apply Loctite(R) to the bolt or stud threads. Follow the Loctite(R) package instructions for best retention. The Loctite(R) 242 material, P/N 12345382 is available from GMSPO.

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.
