Tools Required
J 39400-A Halogen
Leak Detector
Removal Procedure
- Recover the refrigerant. Refer to
Refrigerant Recovery and Recharging
.
- Remove the discharge hose
mounting bolt (2) from the A/C compressor.
- Remove the discharge hose (1) from the A/C compressor.
- Remove the upper radiator baffle. Refer to
Radiator Air Baffle Assemblies and Deflectors
in Engine Cooling.
- Remove the discharge hose
nut from the condenser.
- Remove the discharge hose from the condenser.
- Disconnect the electrical connector from the A/C recirculation
switch.
- Remove the discharge hose from the vehicle.
- Discard all of the used sealing washers. Cap the system openings.
Installation Procedure
- Install the discharge
hose (1) to the vehicle.
- Connect the electrical connector to the A/C recirculation switch.
- Install the discharge
hose to the condenser using new sealing washers.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Install the discharge hose nut to the condenser.
Tighten
Tighten the nut to 16 N·m (12 lb ft).
