REMOVAL

NOTE: Replacement of the 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.

1. Recover the refrigerant.







2. Disconnect the A/C cycling switch electrical connector.







3. Disconnect the evaporator to compressor suction line spring lock coupling from the suction accumulator.
- Discard the O-ring seals.







4. Disconnect the suction accumulator from the evaporator core.
- Discard the O-ring seal.

CAUTION: To prevent damage to the fitting and the tube, use a backup wrench when removing the suction accumulator/drier.

INSTALLATION







1. To install, reverse the removal procedure.
- If a new suction accumulator is to be installed, transfer the A/C cycling switch to the new suction accumulator.
- Lubricate the refrigerant system with the correct amount of clean PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B.
- Install new O-ring seals lubricated in clean PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B.

2. Evacuate, leak test, and charge the refrigerant system.
