Removal and Installation
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 air conditioning system prior to installing a new air conditioning compressor. For additional information, refer to CLIMATE CONTROL SYSTEM-GENERAL INFORMATION AND DIAGNOSIS .
- If A/C flushing equipment is not available, carry out filtering of the air conditioning system after a new air conditioning compressor has been installed. For additional information, refer to CLIMATE CONTROL SYSTEM-GENERAL INFORMATION AND DIAGNOSIS .
- Install a new evaporator core orifice, as directed by the A/C flushing or filtering procedure.
- Install a new suction accumulator as directed by the A/C flushing or filtering procedure.
NOTE:
Installation 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.
- With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING AND LIFTING .
- If flushing of the air conditioning system has not been carried out, recover the refrigerant. For additional information, refer to CLIMATE CONTROL SYSTEM-GENERAL INFORMATION AND DIAGNOSIS .
- Remove the cooling fan motor and shroud. For additional information, refer to ENGINE COOLING .
- Remove the bolts and the drive belt cover.
- Remove the drive belt from the A/C compressor pulley.
- Disconnect the field coil electrical connector.
- Remove the bolts and position aside the power steering line.
- To install, tighten to 13 Nm (10 lb-ft).
- Remove the 3 compressor bolts and lower the A/C compressor.
- Loosen the compressor manifold bolt and remove the A/C compressor.
- Discard the O-ring seals.
- To install, tighten to 21 Nm (15 lb-ft).
- To install, reverse the removal procedure.
- If a new A/C compressor is to be installed, the clutch and clutch field coil must be transferred from the old unit to the new unit. For additional information, refer to CLUTCH AND CLUTCH FIELD COIL in this article.
- If filtering of the refrigerant 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 AND DIAGNOSIS .
- If filtering of the refrigerant 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 AND DIAGNOSIS .
