Suction Accumulator/Drier

NOTE: The suction accumulator/drier should be replaced if the following conditions exist:

• The suction accumulator/drier is perforated.
• The refrigerant system has been open to the atmosphere for one to two months (depends on the relative humidity of the geographic region).
• There is evidence of moisture in the system such as internal corrosion of metal refrigerant lines or if the refrigerant oil is thick and dark.
• There is more than 148ml (5 oz) of refrigerant oil in the suction accumulator/drier indicating that the bleed hole is clogged. This check should be made if the A/C compressor is replaced due to lack of performance (internal damage).

Removal

1. Discharge the refrigerant from the A/C system. Observe all safety precautions. For additional information, refer to Section 12-00.

2. Remove the speed control servo (if equipped).For additional information, refer to Section 10-03.

3. Disconnect the suction hose at the suction accumulator/drier. Cap the suction hose to prevent the entrance of dirt and moisture.

4. Disconnect the wire harness connector from the A/C cyclic switch on top of the suction accumulator/drier and remove the switch.

5. Remove the screw holding the suction accumulator/drier in the A/C accumulator bracket.

6. Disconnect the suction accumulator/drier inlet tube from the A/C evaporator core outlet. Use two wrenches to prevent component damage.

7. Remove the suction accumulator/drier.

Installation

1. Position the suction accumulator/drier to the vehicle.

2. Using a new O-ring lubricated with clean refrigerant oil, connect the suction accumulator/drier inlet tube to the A/C evaporator core outlet. Tighten the connection to 28-36 Nm (21-26 lb-ft) using a backup wrench to prevent component damage.

3. Install the screw in the A/C accumulator bracket.

4. Install the A/C cyclic switch and connect the electrical connector.

5. Using a new O-ring seal lubricated with clean refrigerant oil, connect the suction hose to the A/C compressor. Tighten the connection to 28-36 Nm (21-26 lb-ft).

6. Install the speed control servo, (if equipped). For additional information, refer to Section 10-03.

7. Leak-test, evacuate and charge the system following the recommended service procedures. Observe all safety precautions. For additional information, refer to Section 10-03.

8. Check the system for proper operation.
