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 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. Refrigerant Oil Addition
3. If physical evidence of contamination exists, remove the suction accumulator/drier.
^ Drain the residual refrigerant oil from the suction accumulator/drier and measure the volume for proper oil system matching. Refrigerant Oil Addition
NOTE:
- Installation of a new suction accumulator/drier is not required when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator/drier.
- The suction accumulator/drier and A/C evaporator core orifice cannot be cleaned and new components must be installed.
4. Carry out 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. Air Conditioning System Flushing
^ If A/C system flushing equipment is not available, carry out the Refrigerant System Filtering After A/C Component Replacement. 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 the new A/C compressor.
6. Install the new suction accumulator/drier.
7. Install the new A/C evaporator core orifice.
8. Correctly oil match the system. Refrigerant Oil Addition
9. Evacuate and charge the system. Evacuation and Charging Procedure
