SERVICE MANUAL UPDATE-SEC. 8A CCOT A/C SYSTEM INFORMATION

MODELS AFFECTED: 1991 PARK AVENUE

Missing information for Liquid Line Filter - Page 412 - No. 7 - Expansion (Orifice) Tube/Refrigerant Line (Condenser to Evaporator), replace.

After repeated Orifice Tube plugging or when replacing a seized compressor, replace with a Liquid Line Filter, per Bulletin 90-1-8. The Liquid Line Filter eliminates the need for flushing. The filter is a service part that may only be obtained as an integral part of a condenser to evaporator liquid line assembly. Therefore, to install the filter, the liquid line must be replaced.

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.
