Ford Mustang (1999-2004) Service Manual: 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. 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 A/C compressor must be installed.

Remove and discard the A/C evaporator core orifice. For additional information, refer to Section.

2. Remove the A/C compressor. For additional information, refer to Section.

• Drain the residual refrigerant oil from the A/C compressor and measure the volume for correct system oil matching. For additional information, refer to Refrigerant Oil Adding in this section.

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

Remove the suction accumulator/drier. For additional information, refer to Section.

• Drain the residual refrigerant oil from the suction accumulator/drier and measure the volume for correct oil system matching. For additional information, refer to Refrigerant Oil Adding in this section.

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

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. For additional information, refer to Flushing in this section.
• If A/C system flushing equipment is not available, carry out a system filtering procedure.

  For additional information, refer to Refrigerant Oil Adding After A/C Component Replacement in this section.

5. Install a new A/C compressor. For additional information, refer to Section.

6. Install the new suction accumulator/drier. For additional information, refer to Section.

7. Install the new A/C evaporator core orifice. For additional information, refer to Section.

8. Correctly oil match the system. For additional information, refer to Refrigerant Oil Adding in this section.

9. Evacuate and charge the system. For additional information, refer to Air Conditioning (A/C) System Recovery, Evacuation and Charging in this section.
