REPETITIVE INOP A/C COMPRESSOR - FLUSHING PROCEDURE REVISED

Model(s): All Chevrolet Models with Air Conditioning

Bulletin No.: Chevrolet 87-21

Date: 10/31/1986

SERVICE INFORMATION

If an internal compressor failure is experienced, the expansion (orifice) tube assembly should be removed and checked for contamination of the filter screens. If contamination is noted, flush the system with refrigerant 12 (R-12), following the procedure outlined in the appropriate 1987 Service Manual.

On cars where the expansion tube assembly is remote from the evaporator inlet, the same flushing procedure should be followed and the expansion tube assembly checked for contamination. Repeat the FLUSHING procedure, if required, until the screens on the expansion tube assembly do not indicate new contamination. An in-line filter is being developed for use with remote expansion tube assembly locations.
