The compressor hose and seal washers procedure found in Section "1B" page 31 of the 1992 "Y" Carline Service Manual should note that only Engine Code P used seal washers between the A/C compressor hose and the A/C compressor. Engine Code J will still utilize 0-ring seals between the A/C compressor hose and the A/C compressor. Please make note of this change for future reference.
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.
