REMOVAL

CAUTION:
- If installing a new air conditioning compressor due to an internal failure of the old unit, you must carry out the following procedures to remove contamination from the air conditioning system.
- If A/C flushing equipment is available, carry out flushing of the air conditioning system prior to installing a new air conditioning compressor.
- If A/C flushing equipment is not available, carry out filtering of the air conditioning system after a new air conditioning compressor has been installed.
- Install a new evaporator core orifice, as directed by the A/C flushing or filtering procedure.
- Install a new suction accumulator as directed by the A/C flushing or filtering procedure.

- Refrigerant Compressor Oil (mineral oil) F73Z-19577-AA (Motorcraft YN-9-A) should be used to lubricate R-134a refrigerant system O-ring seals only and should not be added to the R-134a refrigerant system as an A/C compressor lubricant. PAG Refrigerant Compressor Oil F7AZ-19589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B only should be used as an A/C compressor lubricant.

NOTE:
- Installation of a new suction accumulator 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.
- New O-ring seals, lubricated in clean mineral oil, must be installed before reconnecting any A/C fitting which has been disconnected.
