Compressor Fitting HVAC: Service and Repair

REMOVAL
1. Discharge the refrigerant from the system.
2. Loosen nut retaining A/C compressor to condenser discharge line to stud on engine front cover.
3. Raise vehicle on hoist.
4. Remove six retaining screws and engine splash shield.
5. Disconnect wire harness connectors from crankshaft position sensor and A/C compressor.
6. Disengage wire harness retainer from bracket on A/C compressor and position aside.
7. Disconnect A/C manifold and tube using Spring Lock Coupling Disconnect Tool (5/8 inch) T83P-19623-C at A/C compressor to condenser discharge line. Cap the A/C manifold and tube and A/C compressor to condenser discharge line to prevent the entrance of dirt and moisture.
8. Disconnect A/C manifold and tube using Spring Lock Coupling Disconnect Tool (3/4 inch) T85L-19623-A at evaporator to compressor suction line. Cap the A/C manifold and tube and evaporator to compressor suction line to prevent the entrance of dirt and moisture.
9. Remove bolt retaining A/C manifold and tube to A/C compressor and remove A/C manifold and tube from vehicle. Cap the A/C manifold and tube and A/C compressor to prevent the entrance of dirt and moisture.

INSTALLATION
1. Position A/C manifold and tube in vehicle with protective caps installed.
2. Lubricate new O-ring seals with clean Motorcraft YN-12b refrigerant oil or equivalent meeting Ford specification WSH-M1C231-B and position them in the O-ring seal grooves of the A/C compressor.
3. Apply Pipe Sealant with Teflon� D8AZ-19554-A or equivalent meeting Ford specification WSK-M2G350-AZ to threads of manifold retaining bolt.
4. Position A/C manifold and tube assembly to rear head of A/C compressor, making sure A/C manifold and tube pilots are positioned in A/C compressor port openings. Install A/C manifold and tube retaining bolt and tighten bolt to 17-23 N.m (13-16 lb-ft).
5. Connect other ends of suction and discharge lines into system using new O-ring seals lubricated with clean Motorcraft YN-12b refrigerant oil or equivalent meeting Ford specification WSH-M1C231-B.
6. Tighten nut retaining A/C compressor to condenser discharge line to stud on engine front cover.
7. Reattach wire harness to bracket and connect wire harness connectors to crankshaft position sensor and A/C compressor.
8. Install six retaining screws and engine splash shield.
9. Leak-test, evacuate and charge the system. Observe all safety precautions.
