Compressor HVAC: Service and Repair
REMOVALCAUTION: 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.
^ 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.
^ 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 system contamination from a failed A/C compressor or damage to the suction accumulator.
1. If flushing of the air conditioning system has not been performed, recover the refrigerant.
2. Remove the drive belt from the A/C compressor pulley.
3. Raise and support the vehicle.
4. Disconnect the A/C compressor electrical connector.
5. Disconnect the crankshaft position sensor connector.
6. Loosen the bolts and position the A/C compressor to gain access to the manifold and tube bolt.
7. Remove the bolt and detach the manifold and tube assembly.
8. Remove the A/C compressor.
1 Remove the bolts.
2 Remove the A/C compressor.
INSTALLATION
1. To install, reverse the removal procedure.
^ Install new O-rings lubricated in clean PAG oil.
^ If filtering of the air conditioning system is not to be performed, correctly oil match the system with clean PAG oil.
2. If filtering of the refrigerant system is not to be performed, evacuate, leak-test, and charge the refrigerant system.
