Removal

1. Disconnect the battery ground cable.

2. Discharge and recover refrigerant.

• Refer to Refrigerant Recovery in this section.

3. Remove radiator grille.

4. Disconnect pressure switch connector.

5. Disconnect refrigerant line.

• When removing the line connected part, the

connecting part should immediately be plugged
or capped to prevent foreign matter from being
mixed into the line.       

6. Remove bracket bolt.

7. Remove receiver/drier.

• Loosen the bolt, then, using care not to touch or

bend the refrigerant line, carefully pull out the
receiver/drier.

Installation

To install, follow the removal steps in the reverse order,
noting the following points:

1. If installing a new receiver/drier, be sure to add 30cc

(1.0 fl.oz.) of new compressor oil to a new one.

2. Put the receiver/drier in the bracket and connect

with the refrigerant line.  Check that no excessive
force is imposed on the line.  Fasten the bracket bolt
to the receiver/drier.

3. Tighten the refrigerant line to the specified torque.

Torque: 6 N•m (52 lb in)

4. O-rings cannot be reused. Always replace with new

ones.

5. Be sure to apply new compressor oil to the O-rings

when connecting the refrigerant line.
