A/C Compressor Removal/Installation - 3.0L

CAUTION:

When installing a new A/C 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 condition system prior to installing a new air conditioning compressor.
If A/C flushing equipment is not available, carry out the filtering of the air conditioning system after a new air conditioning compressor has been installed. See A/C REFRIGERANT SYSTEM FILTERING AFTER A/C COMPRESSOR REPLACEMENT .
Install a new evaporator core orifice as directed by the A/C flushing or filtering procedure. See EVAPORATOR CORE ORIFICE REMOVAL/INSTALLATION .
Replace the receiver/drier. See A/C RECEIVER/DRIER REMOVAL/INSTALLATION .

NOTE:

Replacement of the 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 the of the refrigerant system has not been performed, recover the refrigerant. See A/C REFRIGERANT SYSTEM TESTS .
Reposition the air intake duct.
1. Loosen the clamp.
2. Disconnect the crankcase ventilation tube.
3. Reposition the air intake duct.

To install, reverse the removal procedure.
- If a new A/C compressor is to be installed, the A/C compressor clutch field coil and the A/C clutch plate must be transferred from the old unit. See A/C COMPRESSOR MAGNETIC CLUTCH REMOVAL/INSTALLATION .
- If filtering the refrigerant system is not to be performed, lubricate the refrigerant system with the correct amount of clean refrigerant oil. See A/C REFRIGERANT OIL ADDITION .
- Evacuate, leak test, and charge the refrigerant system. See A/C REFRIGERANT SYSTEM TESTS .
- Install new O-ring seals lubricated in clean refrigerant oil.
If filtering the refrigerant system is not to be performed, evacuate, leak test, and charge the refrigerant system. See A/C REFRIGERANT SYSTEM TESTS .
