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 A/C 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 Refrigerant Oil Addtion.
3. If physical evidence of contamination exists, remove the suction accumulator/drier.

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

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 a system filtering procedure. 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 Addtion.
9. Perform the Evacuation and Charging Procedure. Evacuation and Charging Procedure
