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.

REMOVAL

SPECIAL SERVICE TOOL(S) REQUIRED

Description Tool Number
Spring Lock Coupling Disconnect Tool (3/4 inch) 412-040 (T85L-19623-A)
Spring Lock Coupling Disconnect Tool (5/8 inch) 412-038 (T83P-19623-C)

1. Discharge A/C system.
2. Remove bolt and nut from radiator coolant recovery reservoir.







3. Disconnect and plug two upper hoses and fittings on radiator coolant recovery reservoir and move reservoir aside to access suction accumulator/drier.

NOTE: Disconnect wire harness from radiator coolant recovery reservoir.







4. Disconnect Suction accumulator/drier inlet tube from A/C evaporator core outlet using 3/4 inch Spring Lock Coupling Disconnect Tool 412-040 (T85L-19623-A). Cap A/C evaporator core outlet to prevent entrance of dirt and moisture.
5. Disconnect A/C manifold and tube from suction accumulator/drier using 5/8 inch Spring Lock Coupling Disconnect Tool 412-038 (T83P-19623-C). Cap A/C manifold and tube to prevent entrance of dirt and moisture.







6. Disconnect wire harness connector from A/C cycling switch on top of suction accumulator/drier.







7. Loosen screw holding suction accumulator/drier in A/C accumulator bracket and remove suction accumulator/drier from A/C accumulator bracket.







8. Remove A/C cycling switch from suction accumulator/drier.

INSTALLATION
1. Install A/C cycling switch on suction accumulator/drier.
2. Position suction accumulator/drier in A/C accumulator bracket.
3. Using new O-ring seals lubricated with clean PAG Compressor Oil Motorcraft YN-12c F7AZ-19589-DA or equivalent meeting Ford specification WSH-M1C231-B, connect suction accumulator/drier inlet tube to A/C evaporator core outlet and A/C manifold and tube to suction accumulator/drier.
4. Tighten screw in A/C accumulator bracket.
5. Connect wire harness connector to A/C cycling switch.
6. Install A/C hose support bracket and retaining nut.
7. Install radiator coolant recovery reservoir and engine ground strap with bolt and nut.
8. Connect hoses to radiator coolant recovery reservoir.
9. Leak-test, evacuate and charge the system. Observe all safety precautions.
10. Check system for proper operation.
