# AIR CONDITIONING NEOPRENE O-RING CHART

ALL 1985-88 MODELS

Attached is a laminated copy of the air conditioning Neoprene O-Ring Chart. This chart will assist dealer personnel in identifying the correct Neoprene Replacement O-Rings and provide some general air conditioning service information.

This chart should be made available to dealer technicians responsible for air conditioning service.

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.
