Compressor HVAC: Service and Repair

REMOVAL

CAUTION: When replacing an A/C compressor which has failed internally, you must perform the following procedures to prevent contamination of the refrigerant system:
- If A/C Flusher or equivalent is available, perform the flushing procedure.
- Replace the A/C evaporator core orifice. For additional information, Expansion Tube, A/C.

NOTE:
- Vehicles that have an inoperative A/C compressor, due to internal causes, must have the refrigerant system cleaned by flushing or filtering. This removes any foreign materials or contaminants that may be present to prevent damage to the new A/C compressor.
- Whenever the A/C compressor is replaced, a new A/C evaporator core orifice must also be installed.
- Installation of a new [1][2]suction accumulator/drier is not required when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator/drier.

1. Disconnect the battery ground cable. For additional information, refer to Battery.
2. Perform the Refrigerant Discharging and Recovery Procedure.
3. Remove the engine drive belt. For additional information, refer to Drive Belts, Mounts, Brackets and Accessories.







4. Disconnect the (A) A/C clutch electrical connector and remove the (B) power steering hose clamp nut.







5. Remove the bolt.







6. Remove the A/C compressor.
1 Remove the bolts.
2 Lift out the A/C compressor.
7. If equipped, transfer the heat shield to the new compressor.

INSTALLATION






















1. To install, reverse the removal procedure.
- Service the new A/C compressor with the proper amount of PAG Compressor Oil, YN-12-C, F7AZ-19589-DA or equivalent meeting Ford specification WSH-M1C231-B. See: Refrigerant Oil Addition.
- Lubricate the new A/C manifold O-rings with PAG Compressor Oil, YN-12-C, F7AZ-19589-DA or equivalent meeting Ford specification WSH-MC1231-B.
