Compressor HVAC: Service Precautions

CAUTION: When the A/C compressor is inoperative due to internal causes, clean the refrigerant system to remove any debris or contaminants to prevent damage to the replacement A/C compressor.

Replacement of the suction accumulator/drier is necessary when the A/C compressor is replaced. The A/C evaporator core orifice should be replaced whenever the A/C compressor is replaced for lack of performance, or when there is debris in the system.

A filter kit should be installed in the refrigerant system prior to the installation of the replacement A/C compressor. The pancake filter, supplied with each kit, should be temporarily installed in the liquid line between the A/C condenser core and the A/C evaporator core orifice. The suction filter, supplied with each kit, should be permanently installed in the suction line between the suction accumulator/drier and the A/C compressor. Install the filters as outlined in the procedure. Filter kit for systems with nylon lined suction hose is Ford part number F2VY-19E773-C.
