This Service Information bulletin supersedes S.I. 64 05 91 (3329) dated August 1991 which should be removed from your S.I. binder and discarded.
SUBJECT:
Air Conditioning Compressors
MODELS:
All
Situation:
Air conditioning compressors which are returned to the Warranty Parts Return Center are being received without shipping caps on the inlet and outlet fittings.
Because both R-12 refrigerant and refrigerant oils are hygroscopic, moisture from the air starts a rusting process very quickly in the compressor, making meaningful failure analysis impossible.
Return the failed compressor in the packaging supplied with the replacement unit to prevent damage in transit. Compressors returned to the Warranty Parts Return Center without both inlet and outlet fittings sealed with the plastic caps from the replacement compressor will have to be returned to the dealer.
Please adhere to the above procedure to prevent debit action.
