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. Install a new Thermostatic Expansion Valve (TXV).
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 Adding. Refrigerant Oil Addition
3. Remove the receiver/drier.
- Drain the residual refrigerant oil from the receiver/drier and measure the volume for correct oil system matching. For additional information, refer to Refrigerant Oil Adding. Refrigerant Oil Addition

NOTE: The thermostatic expansion valve cannot be cleaned and a new thermostatic expansion valve 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 condenser core by flushing. For additional information, refer to 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 receiver/drier, if necessary.
7. Install the new TXV.
8. Correctly oil match the system. For additional information, refer to Refrigerant Oil Adding. Refrigerant Oil Addition
9. Evacuate and charge the system. For additional information, refer to Evacuation and Charging. Evacuation and Charging Procedure
