Inspection/Assembly Requirements-Following Compressor Failure

CAUTION: To prevent refrigerant system contamination and possible failure of the replacement A/C compressor, perform 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 must be replaced.

2. Remove the A/C compressor.
- Drain the residual refrigerant oil from the A/C compressor and measure the volume for proper system oil matching.
3. Remove the suction accumulator/drier.
- Drain the residual refrigerant oil from the suction accumulator/drier and measure the volume for proper oil system matching.

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

4. Perform 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.
- If A/C system flushing equipment is not available, perform a system filtering procedure.

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

5. Install the replacement A/C compressor.
6. Install the replacement suction accumulator/drier.
7. Install the replacement A/C evaporator core orifice.
8. Properly oil match the system.
9. Evacuate and charge the system. Evacuation and Charging
