AIR CONDITIONING COMPRESSOR REPLACEMENT PROCEDURE
All 1988 Rivieras/Reattas are equipped with a refrigerant system filter within the compressor hose assembly muffler (Illustration). This filter eliminates the need to flush the A/C system after a compressor failure.
When replacing a compressor on a 1988 Riviera/Reatta:
1. Replace the compressor hose assembly, Part Number 1644314.
2. Inspect the orifice tube for debris and, if necessary, clean or replace it.
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.
