Compressor

REMOVAL

CAUTION: If installing a new air conditioning compressor due to an internal failure of the old unit, you must carry out the following procedures to remove contamination from the air conditioning system.
- If A/C flushing equipment is available, carry out the flushing of the air conditioning system prior to installing a new air conditioning compressor.
- If A/C flushing equipment is not available, carry out filtering of the air conditioning system after a new air conditioning compressor has been installed.
- Install a new evaporator core orifice as directed by the A/C flushing or filtering procedure.
- Install a new suction accumulator as directed by the A/C flushing or filtering procedure.

NOTE: Installation of a new suction accumulator 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.

1. If flushing of the air conditioning system has not been performed, recover the refrigerant.
2. Turn the air suspension off.
3. Raise the vehicle on a hoist.
4. Remove the drive belt from the A/C clutch pulley.







5. Disconnect the wire harness connector from the crankshaft position sensor.







6. Disconnect the connector.







7. Disengage the wire harness retainer from the bracket.







8. Remove the bolts and lower the A/C compressor.







9. Remove the bolt and detach the manifold and tube from the A/C compressor.
- Discard the O-ring seals.







10. Remove the bolt and remove the bracket from the A/C compressor.

INSTALLATION
1. To install, reverse the removal procedure.
- If filtering of the refrigerant system is not to be performed, install the correct amount of PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B.
- Lubricate the O-ring seal with PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B.

2. If filtering of the refrigerant system is not to be performed, evacuate, charge and leak test the refrigerant system.
