SECTION: 1D
CIERA

This bulletin supersedes Dealer Management Bulletin 85-I-15 dated January 31,1985.

The return program involving V-5 air conditioning compressors terminated September 1, 1985. Some service compressors however, still contain information regarding the return program. This return information should be disregarded.

When repairing the V-5 compressor, it is suggested that you use the diagnostics contained in the 1986 Chassis Service Manual.. The 1986 diagnostics are improved over the 1985 Chassis Service Manual, but will also pertain to the 1985 models. It is suggested that a notation be made in your 1985 Chassis Service Manual to refer to the diagnostic charts on pages 1B-8 to 1B-11 of the 1986 Chassis Service Manual.

A number of compressors have been replaced that only have a defective control valve. By following the diagnostic charts in the 1986 Chassis Service Manual, failures of this valve will be discovered and the need for compressor replacement will be eliminated.




For your convenience, attached is a Service Parts list for the V-5 compressor models currently released along with a labeled exploded view.
