Inspection and Assembly Requirements

INSPECTION AND ASSEMBLY REQUIREMENTS

CAUTION: To prevent refrigerant system contamination and possible failure of the new A/C compressor, carry out the following procedures:

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 compressor must be installed.

1. Remove and discard the A/C 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 correct system oil matching. For additional information, see REFRIGERANT OIL ADDING.

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

3. Remove the suction accumulator.
1. Drain the residual refrigerant oil from the suction accumulator/drier and measure the volume for correct oil system matching. For additional information, see REFRIGERANT OIL ADDING.

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

4. Carry out an A/C system flushing or filtering procedure:
1. If A/C system flushing equipment is available, clean the A/C evaporator core and the A/C condenser core by flushing.
2. If A/C system flushing equipment is not available, carry out the Refrigerant System Filtering After A/C Compressor Replacement in this section. For additional information, see REFRIGERANT SYSTEM FILTERING FOLLOWING AIR CONDITIONING (A/C) COMPONENT INSTALLATION.

5. Install the 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. For additional information, see REFRIGERANT OIL ADDING.
9. Evacuate and charge the system.
