A/C INSPECTION AND ASSEMBLY REQUIREMENTS - FOLLOWING COMPRESSOR FAILURE

CAUTION:To prevent refrigerant system contamination and possible failure of the replacement A/C compressor, perform the following procedures.
NOTE:A dirty 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.
1. Remove and discard the evaporator core orifice. See Service and Repair.

2. Remove the A/C compressor. See - Removal and Replacement, or - Removal and Replacement.

- Drain the residual refrigerant oil from the A/C compressor and measure the volume for proper system oil matching. See A/C Refrigerant Oil Addition.

3.
NOTE:The suction accumulator/drier and A/C evaporator core office cannot be cleaned and a new A/C evaporator core office must be installed.Remove the suction accumulator/drier. See Service and Repair.

- Completely drain the residual refrigerant oil from the receiver/drier, (see A/C Refrigerant Oil Addition) and measure the volume for proper oil system matching.

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

4. Perform 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. Follow the instructions included with the flushing equipment.
NOTE:System flushing must be performed prior to the installation of the replacement A/C compressor. Flush only the evaporator core and condenser core. Do not flush the receiver/drier, evaporator core orifice, hoses and mufflers. Hoses can be reused unless they contain debris.
- If A/C system flushing equipment is not available, perform the refrigerant system filtering after A/C compressor replacement procedure. See A/C Refrigerant System Filtering After A/C Compressor Replacement

5. Install the replacement A/C compressor. See - Removal and Replacement, or - Removal and Replacement.

6. Install the replacement receiver/drier. See Service and Repair.

7. Install the replacement evaporator core orifice. See Service and Repair.

8. Properly oil match the system. See A/C Refrigerant Oil Addition.

9. Evacuate and charge the system. See A/C Refrigerant System Tests.
