- Before servicing the vehicle, refer to the Precautions section.
- Disconnect battery negative cable from battery and properly isolate to prevent accidental reconnection.
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:
NOTEInstallation of a new suction accumulator is not required when repairing the air conditioning system, except when there is physical evidence of contamination from a failed A/C compressor or damage to the suction accumulator.
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 flushing of the air conditioning system has not been carried out, recover the refrigerant.
- Remove the drive belt from the A/C compressor pulley.
- Disconnect the field coil electrical connector.
- Loosen the bolt and detach the compressor manifold and tube assembly from the A/C compressor.
- Discard the O-ring seals.
- Raise the vehicle.
- Disconnect the crank sensor electrical connector.
- Remove the nut and detach the wiring harness clips.
Remove the studs and the A/C compressor.
- Install new O-ring seals lubricated in clean PAG 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.
- If filtering of the refrigerant system is not to be carried out, evacuate, charge and leak test the refrigerant system.
Install or connect the following:
A/C compressor studs and torque to 18 ft. lbs. (25 Nm)
- Partially refill the system and check for leaks.
- If no leaks are present, complete refrigerant charging.
