Removal and Installation

NOTICE: If installing a new air conditioning (A/C) compressor due to an internal failure of the old unit, carry out the following procedures to remove contamination from the A/C system. Failure to remove contamination from the A/C system, if present, will result in poor A/C performance and/or damage to the new A/C compressor and other components.

If A/C flushing equipment is available, carry out flushing of the A/C system prior to installing a new A/C compressor.

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.

Install a new thermostatic expansion valve (TXV), as directed by the A/C flushing or filtering procedure.
Install a new receiver/drier as directed by the A/C flushing or filtering procedure.

NOTE: Installation of a new receiver/drier is not required when repairing the A/C system, except when there is physical evidence of contamination from a failed A/C compressor or damage to the receiver/drier. Damage to the receiver/drier includes leaks in the receiver/drier, physical damage to the receiver/drier shell or desiccant, or moisture contamination. Moisture contamination results only from a complete loss of refrigerant and equalization of the refrigerant system pressure with atmospheric pressure for a period longer than one hour. If even a slight amount of positive refrigerant pressure is present in the system before repairs are carried out, the receiver/drier should not be replaced.

NOTE: A new A/C compressor may come equipped with an A/C clutch disc and hub, A/C compressor pulley and A/C clutch field coil already installed. If these components are not pre-installed, it will be necessary to transfer these parts from the old A/C compressor to the new compressor prior to installation of the A/C compressor if suitable for reuse.

With the vehicle in NEUTRAL, position it on a hoist.

If flushing of the A/C system has not been carried out, recover the refrigerant.
Release the tensioner and remove the drive belt from the A/C compressor pulley.

Remove the 3 compressor splash shield pin-type retainers and the splash shield.

Remove the A/C compressor suction and discharge fitting nuts and disconnect the fittings.
Discard the O-ring seals and gasket seals.
To install, tighten to 15 Nm (11 lb-ft).
Disconnect the A/C clutch field coil electrical connector.
Remove the A/C compressor nut.
To install, tighten to 25 Nm (18 lb-ft).
Completely loosen the A/C compressor mounting stud.
To install, tighten to 9 Nm (80 lb-in).
Remove the 2 A/C compressor bolts.
To install, tighten to 25 Nm (18 lb-ft).
Remove the A/C compressor.

To install, reverse the removal procedure.
If a new A/C compressor is to be installed, the clutch assembly may need to be transferred from the old unit to the new unit.

Install new gasket seals and O-ring seals.
If filtering of the refrigerant system is not to be carried out, lubricate the refrigerant system with the correct amount of clean PAG oil.
If filtering of the refrigerant system is not to be carried out, evacuate, leak test and charge the refrigerant system

It calls for 1.1 labor hours to replace it not counting the evacuate and recharge or other related procedures.
