Subject: LOSS OF A/C FUNCTION DUE TO A/C PIPE CRACKING


1986-87 SUNBIRD MODEL WITH 1.8L L4 OHC (VIN 0) OR 2.0L L4 OHC (VIN K) AND A/C

Some customers may comment about a lack of air conditioning function. This may be due to a crack in the A/C discharge line between the compressor block fitting and the A/C muffler, causing a loss of refrigerant.

If this condition is diagnosed, the compressor suction and discharge hose assembly should be replaced following the procedure in Section 1B1 of the chassis service manual, and the system charged with refrigerant following the procedure in Section 1B of the chassis service manual. After the replacement hose assembly has been installed and the system has been charged, the A/C system should be checked for proper function.




To prevent this condition from reoccurring, a service brace kit, P/N 22545036, should be installed. See Figure 1.

NOTICE: In order to install the brace kit, it will be necessary to remove the RH splash shield for proper access to the compressor.

Warranty Information
