A/C Compressor Removal / Installation - 4.0L
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 as directed by the A/C flushing or filtering procedure. 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 of the refrigerant system has not been performed, recover the refrigerant. See A/C REFRIGERANT SYSTEM TESTS .
- Remove the accessory drive belt from the A/C compressor pulley. See DRIVE BELT REMOVAL / INSTALLATION - 4.0L .
- Remove the bolts and detach the power steering fluid reservoir.
- Remove the bolts and the bracket.
- Disconnect the electrical connector.
- Loosen the bolt and disconnect the compressor manifold and tube assembly from the A/C compressor.
- Remove the pin-type retainers and position the inner fender well access cover aside.
NOTE:
- The two lower nuts and studs are accessible through the inner fender well.
- Remove the four nuts, four studs, and the A/C compressor.
- Discard the O-ring seals.
- 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 .
- 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.
- Evacuate, leak test, and charge the refrigerant system. See A/C REFRIGERANT SYSTEM TESTS .
