Removal and Installation

WARNING: This page is about a different car, the 2004 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.

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. For additional information, refer to CLIMATE CONTROL SYSTEM-GENERAL INFORMATION .
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. For additional information, refer to CLIMATE CONTROL SYSTEM-GENERAL INFORMATION .
Install a new evaporator core orifice (19D990) as directed by the AIR CONDITIONING (A/C) SYSTEM FLUSHING procedure.
Install a new suction accumulator (19C836) as directed by the AIR CONDITIONING (A/C) SYSTEM FLUSHING procedure.

CAUTION: Refrigerant compressor oil (mineral oil) F73Z-19577-AA (Motorcraft YN-9-A) should be used to lubricate R-134a refrigerant system O-ring seals only and should not be added to the R-134a refrigerant system as an A/C compressor lubricant. PAG refrigerant compressor oil F7AZ-19D589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B only should be used as an A/C compressor lubricant.

NOTE: If installing a new A/C compressor, the A/C clutch disc and hub (19D786), A/C compressor pulley (19D784) and A/C clutch field coil (19D798) must be inspected and transferred from the old unit to the new unit if suitable for reuse.

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.

If flushing of the refrigerant system has not been carried out, recover the refrigerant. For additional information, refer to CLIMATE CONTROL SYSTEM-GENERAL INFORMATION .
Remove the drive belt from the A/C compressor pulley.
Disconnect the electrical connector.

To install, reverse the removal procedure.
- If a new A/C compressor is to be installed, the clutch assembly must be transferred from the old unit to the new unit. For additional information, refer to CLUTCH AND CLUTCH FIELD COIL .
- Install new O-ring seals lubricated in clean mineral oil.
- If filtering of the refrigerant system is not to be carried out, lubricate the refrigerant system with the correct amount of clean PAG oil. For additional information, refer to CLIMATE CONTROL SYSTEM-GENERAL INFORMATION .
If filtering of the refrigerant system is not to be carried out, evacuate, leak test and charge the refrigerant system. For additional information, refer to CLIMATE CONTROL SYSTEM-GENERAL INFORMATION .
