Inspection and Assembly Requirements Following an A/C Compressor Failure

CAUTION: To prevent refrigerant system contamination and possible failure of the new A/C compressor, carry out the following procedures:

1. Remove and discard the A/C evaporator core orifice.

NOTE: A dirty A/C evaporator core orifice or a condenser to evaporator tube containing black refrigerant oil and particles indicates that the A/C compressor has failed and a new compressor must be installed.

2. Remove the A/C compressor.
- Drain the residual refrigerant oil from the A/C compressor and measure the volume for correct system oil matching. For additional information, refer to the Refrigerant Oil Addition procedure. Refrigerant Oil Addition

3. Remove the suction accumulator/drier.
- Drain the residual refrigerant oil from the suction accumulator/drier and measure the volume for correct oil system matching. For additional information, refer to Refrigerant Oil Addition. Refrigerant Oil Addition

NOTE: The suction accumulator/drier and A/C evaporator core orifice cannot be cleaned and new components must be installed.

4. Carry out an A/C system flushing or filtering procedure:
- If A/C system flushing equipment is available, clean the A/C evaporator core and the A/C condenser core by flushing. For additional information, refer to Air Conditioning (A/C) System Flushing. Air Conditioning System Flushing
- If A/C system flushing equipment is not available, carry out the Refrigerant System Filtering After A/C Compressor Replacement in this section. For additional information, refer to Refrigerant System Filtering After A/C Component Replacement. Refrigerant System Filtering After A/C Component Replacement

NOTE: System flushing is the preferred method of cleaning. However, if flushing equipment is not available, carry out system filtering.

5. Install the new A/C compressor.
6. Install the new suction accumulator/drier.
7. Install the new A/C evaporator core orifice.
8. Correctly oil match the system. For additional information, refer to Refrigerant Oil Addition. Refrigerant Oil Addtion
9. Evacuate and charge the system. For additional information, refer to Evacuation and Charging. Evacuation and Charging Procedure
