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. Refrigerant Oil Addtion

3. Remove the suction accumulator.
- Drain the residual refrigerant oil from the suction accumulator and measure the volume for correct oil system matching. Refrigerant Oil Addtion

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

4. Carry out an A/C system flushing or filtering procedure:
- If A/C system flushing equipment is available, clean the evaporator core and the condenser core by flushing. Air Conditioning System Flushing
- If A/C system flushing equipment is not available, carry out a system filtering procedure. 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 a new A/C compressor.
6. Install the new suction accumulator.
7. Install the new A/C evaporator core orifice.
8. Correctly oil match the system. Refrigerant Oil Addtion
9. Evacuate and charge the system. Evacuation and Charging Procedure
