Removal and Installation
WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. 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 flushing of the A/C system prior to installing a new A/C compressor. For additional information, refer to CLIMATE CONTROL SYSTEM-GENERAL INFORMATION .
- If A/C flushing equipment is not available, carry out filtering of the A/C system after a new A/C compressor has been installed. For additional information, refer to CLIMATE CONTROL SYSTEM-GENERAL INFORMATION .
- Install a new evaporator core orifice, as directed by the A/C flushing or filtering procedure.
- Install a new suction accumulator (19C836) as directed by the A/C flushing or filtering 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-19589-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, A/C compressor pulley and A/C clutch field coil 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.
- With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING AND LIFTING .
- If flushing of the A/C 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 clutch field coil electrical connector.
- Remove the compressor manifold bolt.
- To install, tighten to 20 Nm (15 lb-ft).
- Disconnect the manifold.
- Discard the O-ring seals.
- Remove the 2 A/C compressor nuts.
- To install, tighten to 25 Nm (18 lb-ft).
- Remove the 2 A/C compressor studs.
- To install, tighten to 13 Nm (10 lb-ft).
- Remove the A/C compressor nut and stud.
- To install, tighten to 25 Nm (18 lb-ft).
- Position forward the right front wheelhouse opening panel-to-frame insert.
- Remove the A/C compressor.
- Remove the A/C compressor through the right front wheel house opening.
- 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 A/C 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 A/C 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 .
