Receiver Dryer: Service and Repair

Suction Accumulator/Drier - Explorer 5.OL

SPECIAL SERVICE TOOL(S) REQUIRED

Removal

1. Disconnect battery ground cable.

2. NOTE: The suction accumulator/drier should be replaced whenever a major component of the refrigerant system is replaced.

Discharge the refrigerant from the A/C system.

3. Disconnect the electrical connector from the A/C cycling switch.













4. Remove the A/C cycling switch by unscrewing it from the suction accumulator/drier.

5. Disconnect the suction accumulator/drier, using Spring Lock Coupling Disconnect Tool T85L-19623-A, and cap the openings to prevent the entry of dirt and moisture.

6. Loosen the fitting connecting the suction accumulator/drier to the A/C evaporator core. Use a backup wrench to prevent component damage.

7. Remove the two screws and two studs from the A/C evaporator housing bracket, and the screw holding the inlet tube to the A/C evaporator housing bracket.

8. Disconnect the suction accumulator/drier from the A/C evaporator core and remove the A/C evaporator housing bracket from the suction accumulator/drier.

Installation

1. Position the A/C evaporator housing bracket on the new suction accumulator/drier loosely.





2. Use a new 0-ring lubricated with clean refrigerant oil to connect the suction accumulator/drier to the inlet tube while aligning the A/C evaporator housing bracket to the A/C evaporator housing.

3. Tighten the suction accumulator/drier fitting to 35-42 N.m (26-31h-ft) using a backup wrench. Install the A/C evaporator housing bracket to the A/C evaporator housing. Tighten the A/C evaporator housing bracket on the accumulator, and reinstall the clamp that holds the inlet tube to the A/C evaporator housing bracket.

4. Connect the suction hose to suction accumulator/drier. Check for a missing or a damaged garter spring and replace if necessary. Install two new specified (special material) 0-rings lubricated with clean refrigerant oil onto the male fitting.

5. Use a new 0-ring lubricated with clean refrigerant oil on the nipple of the suction accumulator/drier. Install the A/C cycling switch and tighten to 7-13 N-m (62-115 lb-in) if it has a metal base. Hand-tighten only if A/C cycling switch has a plastic base.

6. Connect A/C cycling switch electrical connector.

7. NOTE: When battery voltage is removed from the powertrain control module (PCM), all learned values will be cleared and reset to predetermined values. When battery voltage is restored to the PCM, the vehicle may exhibit certain driveability concerns. It will be necessary to drive the vehicle to allow the PCM to relearn values for optimum driveability and performance.

Connect the battery ground cable.

8. Leak test, evacuate and charge the system.

9. Check the system for proper operation.
