J 39400-A Halogen Leak
Detector
Removal Procedure
- Recover the refrigerant from the system. Refer to
Refrigerant Recovery and Recharging
.
- Disconnect the negative battery cable. Refer to
Battery Negative Cable Disconnection and Connection
in Engine Electrical.
- Remove the accessory drive belt. Refer to
Drive Belt Replacement
in Engine Mechanical.
- Raise and support the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the right front tire. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Remove the front air deflector. Refer to
Front Air Deflector Replacement
in Body Front End.
- Remove the right fascia extension. Refer to
Front Bumper Fascia Extension Replacement
in Body Front End.
- Disconnect the brake line retaining clips from the engine frame in order
to allow the brake lines to move during removal of the A/C compressor.
Important: Seal the A/C compressor suction and discharge ports after the hoses are removed
in order to keep contaminants from entering the A/C compressor and oil from draining
out of the A/C compressor during removal.
- Remove the nut (2) from the discharge hose (3) and disconnect
the discharge hose (3) from the A/C compressor.
- Remove the nut (2) from the suction hose (1) and disconnect
the suction hose fitting (1) from the A/C compressor.
- Disconnect the A/C compressor electrical
connector.
- Remove the A/C compressor mounting fasteners (1,
2, 3, 4).
- Remove
the A/C compressor (2) mounting stud (1).
- Rotate the A/C compressor in order to allow the A/C compressor to exit through
the wheelhouse opening.
- Remove the A/C compressor from the vehicle.
Important: If replacing the compressor, balance the compressor oil. Refer to
Compressor Oil Balancing
.
Installation Procedure
- Install the A/C compressor through the wheelhouse opening.
- Position
the A/C compressor (2) on the mounting surface.
- Install the A/C compressor mounting stud (1) through the appropriate
compressor mounting boss.
- Install the A/C compressor mounting fasteners (1,
2, 3, 4) and hand tighten the fasteners.
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.
- Tighten the fasteners in the following sequence:
Tighten
- Tighten the A/C compressor mounting stud nut (1) to 50 N·m
(37 lb ft).
- Tighten the upper rear A/C compressor mounting bolt (3) to 50 N·m
(37 lb ft).
- Tighten the front A/C compressor mounting bolt (2) to 50 N·m
(37 lb ft).
- Tighten the last lower rear A/C compressor mounting bolt (4) to
25 N·m (18 lb ft).
Important: Inspect the seal washers for damage before reinstalling the A/C lines.
If any damage is noted during inspection, the suspect seal must be replaced.
Flat washer type seals do not require lubrication.
- Connect the A/C compressor electrical connector.
- Connect the suction hose (1) to the A/C compressor.
- Install the suction hose nut (2) to the A/C compressor.
Tighten
Tighten the nut to 16 N·m (12 lb ft).
- Connect the discharge hose (3) to compressor.
- Install the discharge hose nut (2).
Tighten
Tighten the nut to 16 N·m (12 lb ft).
- Reconnect the brake line retaining clips to the frame.
- Install the accessory drive belt. Refer to
Drive Belt Replacement
in Engine Mechanical.
- Install the fascia extension. Refer to
Front Bumper Fascia Extension Replacement
in Body Front End.
- Install the front air deflector. Refer to
Front Air Deflector Replacement
in Body Front End.
- Reinstall the right front tire. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Lower the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Connect the negative battery cable. Refer to
Battery Negative Cable Disconnection and Connection
in Engine Electrical.
- Recharge the A/C system. Refer to
Refrigerant Recovery and Recharging
.
- Leak test the fittings of the component using J 39400
.
