Compressor HVAC: Service and Repair

REMOVAL

CAUTION: When an A/C compressor 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.
- Install a new A/C evaporator core orifice.

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 a new A/C compressor is installed, a new A/C evaporator core orifice must also be installed.
- Installation of a new 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. Prepare the vehicle for A/C compressor removal.
1 Disconnect the battery ground cable.
2 Perform the Refrigerant Discharging and Recovery Procedure to remove the refrigerant.
3 Remove the drive belt from the A/C pulley.







2. Remove the bolts. Detach the power steering fluid reservoir.







3. Remove the bolts and the bracket.







4. Disconnect the A/C clutch field coil electrical connector.







5. Remove the bolt. Disconnect the A/C manifold and tube. Remove and discard the O-ring seals.
- During installation, install new O-ring seals lubricated with PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B.







6. Remove the retaining pins. Position the inner fender well access panel out of the way.







7. Remove the four nuts, four studs, and the A/C compressor.
- The lower two nuts and two studs are accessible through the inner fender well.

INSTALLATION
1. To install, reverse the removal procedure.
- If a new A/C compressor is to be installed, the A/C clutch field coil and the A/C clutch must be transferred from the old unit.
- If a new A/C compressor is to be installed, refer to refrigerant oil addition. See: Refrigerant Oil Addition.

2. Evacuate, leak test, and charge the A/C system.
