Compressor HVAC: Service and Repair
NOTE: Whenever a compressor is replaced, it will be necessary to replace the suction accumulator/drier.REMOVAL
1. Recover the refrigerant from the A/C system following the recommended service procedures. Observe all safety precautions.
2. Disconnect the compressor clutch wires at the field coil connector on the compressor.
3. Remove the accessory drive belt.
4. Disconnect the hose assemblies from the condenser and the suction line.
5. Remove the four A/C compressor bolts from the A/C compressor mounting bracket.
6. Remove the compressor and the manifold and tube assembly from the vehicle as a unit. The assembly will not clear the subframe and the radiator support if an attempt is made to remove the unit from the bottom. It must be removed from the top.
7. Remove the manifold and tube assembly as an on-bench operation.
8. If the old compressor is to be replaced with a new one, remove the clutch and field coil assembly.
INSTALLATION
1. The new service replacement FX-15 and 10P15F compressors contain 240 ml (8 oz) of specified refrigerant oil. Before the replacement compressor installation drain 120 ml (4 oz) of refrigerant oil from the compressor. This will maintain the total system oil charge within the specified limits.
2. Install the manifold and tube assembly on the A/C compressor (two bolts).
3. Install the compressor and the manifold and tube assembly on the A/C mounting bracket (four bolts).
4. Using new O-rings lubricated with clean refrigerant oil, connect the suction line to the compressor manifold and tube assembly. Attach the discharge line to the A/C condenser.
5. Connect the clutch wires to the field coil connector.
6. Install the accessory drive belt. Adjust the belt tension.
7. Leak test, evacuate, and charge the A/C system following the recommended service procedures. Observe all safety precautions.
8. Check the A/C system for proper operation.
