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 the A/C condenser core, the A/C compressor, the A/C evaporator core, or a refrigerant hose/line. An A/C evaporator core orifice or 0-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.

CAUTION: 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 1/2 inch holes in the bottom of the old suction accumulator/drier to make sure 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 the refrigerant from the A/C system. Observe all safety precautions.






2. Remove the bolt and nut from the radiator coolant recovery reservoir and move the reservoir aside to access the suction accumulator/drier.






3. Remove the nut retaining the A/C hose support racket.
4. Disconnect the suction accumulator/drier inlet tube from the A/C evaporator core outlet using the Spring Lock Coupling Disconnect Tool (5/8 inch) T83P-19623-C. Cap the A/C evaporator core outlet to prevent the entrance of dirt and moisture.
5. Disconnect the A/C manifold and tube from the suction accumulator/drier using the Spring Lock Coupling Disconnect Tool (5/8 inch) T83P-19823-C. Cap the A/C manifold and tube to prevent the entrance of dirt and moisture.






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






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






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

INSTALLATION
1. Install the A/C cycling switch on the suction accumulator/drier.
2. Position the suction accumulator/drier in the A/C accumulator bracket.
3. Using new 0-ring seals lubricated with clean refrigerant oil, connect the suction accumulator/drier inlet tube to the A/C evaporator core outlet and the A/C manifold and tube to the suction accumulator/drier.
4. Install the screw in the A/C accumulator bracket.
5. Connect the wiring harness connector to the A/C cycling switch.
6. Install the A/C hose support bracket and the retaining nut.
7. Install the radiator coolant recovery reservoir with the bolt and nut.
8. Leak-test, evacuate, and charge the system. Observe all safety precautions.
9. Check the system for proper operation.
