Removal and Installation
NOTE: Replacement of the 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 should be replaced if one of these conditions exist:
- The suction accumulator/drier is perforated.
- The refrigerant system has been opened to the atmosphere for a period of time longer than required to make a minor repair.
- There is evidence of moisture in the system such as internal corrosion of metal refrigerant lines or the refrigerant oil is thick and dark.
NOTE: The compressor oil from vehicles equipped with an FS-10 A/C compressor may have a dark color while maintaining a normal oil viscosity. This is normal for this A/C compressor because carbon from the A/C compressor piston rings will discolor the oil.
When replacing the suction accumulator/drier, the procedure given here must be followed to make sure the total oil charge in the system is correct after the new suction accumulator/drier is installed.
- Drain the oil from the removed suction accumulator/drier into a suitable measuring container: Drill one or two 13 mm (1/2 inch) holes in the bottom of the old suction accumulator/drier to make sure all the oil has drained out.
- Add the same amount plus 60 ml (2 ounces) of clean new PAG Compressor Oil Motorcraft YN-12c F7AZ-19589-DA or equivalent meeting Ford specification WSH-M1C231-B to the new suction accumulator/drier.
