A/C Compressor Front Seal Leakage

(Supersedes 88-038, dated DEC 1988)

SYMPTOM

The A/C warning light comes on intermittently and/or the compressor clutch is slipping.

The customer complaint may be that the A/C is performing poorly (if they do not notice the warning light is on).

CORRECTIVE ACTION

If the warning light is coming on or the A/C clutch is slipping, check the shaft seal for leakage, usually the clutch and pulley will be coated with burnt oil if the seal is leaking.

Replace the A/C compressor seal as described in section 22 of the Service Manual.

The following guidelines should be followed in addition to those in the manual:

^ Keep the shaft and housing clean. Use brake/contact cleaner for final cleaning before reassembly.

^ Lubricate the seal and seat with compressor oil.

^ The O-ring is packaged with a felt seal, so make sure the O-ring is not contaminated with lint from the felt seal.

^ Install a new style compressor clutch set.

^ Check the air gap clearance (should be 0.4 - 0.6 mm).

^ To be sure the compressor oil level is correct, add 20cc Suniso 5GS (or equivalent) refrigerant oil.

^ Make sure the A/C wire harness is the latest design (reter to Service Bulletin 88-015 in the Accessories section). If not, update the harness.
