Removal and Installation

CAUTION: Replacement of the suction accumulator/drier is necessary any time a major component of the refrigerant system is replaced. Failure to replace the suction accumulator/drier will expose the refrigerant system to excessive moisture accumulation. A major component includes A/C condenser core, A/C compressor, A/C evaporator core or a refrigerant hose/line. An A/C evaporator core orifice or O-ring seal is not considered a major component but the A/C evaporator core orifice should be replaced whenever the A/C compressor is replaced for lack of performance.

In addition to the preceding condition, the suction accumulator/drier should also be replaced if one of the following 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 that 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 ensure that all the oil has drained out.
- Add the same amount plus 60 ml (2 ounces) of clean new Motorcraft YN-12b refrigerant oil or equivalent meeting Ford specification WSH-M1C231-B to the new suction accumulator/drier.





REMOVAL
1. Recover refrigerant from A/C system following recommended service procedures. Observe all safety precautions. Discharging and Recovery
2. Disconnect refrigerant tubes from suction accumulator/drier. Use Spring Lock Coupling Disconnect Tool (3/4 inch) T85L-19623-A.
3. Disconnect wire harness connector from A/C cycling switch on the side of suction accumulator/drier.
4. Remove nut holding suction accumulator/drier in suction accumulator/drier bracket and remove suction accumulator/drier.

INSTALLATION
1. Position suction accumulator/drier for installation.
2. Using new O-rings lubricated with clean Motorcraft YN-12b refrigerant oil or equivalent meeting Ford specification WSH-M1C231-B, connect refrigerant tubes.
3. Install nut onto suction accumulator/drier bracket.
4. Connect electrical connector to A/C cycling switch.
5. Connect refrigerant tubes to suction accumulator/drier.
6. Leak test, evacuate, and charge the system following recommended service procedures. Observe all safety precautions.
7. Check system for proper operation.
