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 accessary 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 fastener (2)
from the discharge hose (3) and disconnect the discharge hose (3)
from the A/C compressor.
- Remove the fastener (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.
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路m
(37 lb ft).
- Tighten the upper rear A/C compressor mounting bolt (3)
to 50 N路m (37 lb ft).
- Tighten the front A/C compressor mounting bolt (2) to 50 N路m
(37 lb ft).
- Tighten the last lower rear A/C compressor mounting bolt (4)
to 25 N路m (18 lb ft).
Important: Inspect the seal washers for damage before reinstalling the A/C lines
and hoses.
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.
Tighten
Tighten the suction hose fastener (2) to 16 N路m (12 lb ft).
- Connect the discharge
hose (3) to compressor and install the fastener (2).
Tighten
Tighten the discharge hose fastener (2) to 16 N路m (12 lb ft).
- Reconnect the brake line retaining clips to the frame.
- Install the accessary 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 component using J 39400
.
