A/C Inspection and Assembly Requirements

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.
2. Remove the A/C compressor.
1. 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.

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

3. Remove the suction accumulator/drier, see A/C RECEIVER / DRIER REMOVAL / INSTALLATION.
1. 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.
6. Install the replacement receiver/drier. See A/C RECEIVER / DRIER REMOVAL / INSTALLATION.
7. Install the replacement evaporator core orifice.
8. Properly oil match the system, see A/C REFRIGERANT OIL ADDITION.
9. Evacuate and charge the system, see A/C REFRIGERANT SYSTEM TESTS.
