Removal Procedure
Tools Required
J 38042 Dual O-Ring
Separator
Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing
any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to
the vehicle or its components.
- Disconnect
the negative battery cable.
- Recover the refrigerant. Refer toRefrigerant Recovery and Recharging
.
- Remove the grille. Refer to
Air Inlet Grille Panel Replacement
.
- Remove the bolt.
- Disconnect the hose assembly from the top of the compressor.
- Remove the sealing washers.
- Disconnect the hose assembly from the accumulator using the J 38042
.
- Remove the O-Ring seals from the accumulator hose.
- Disconnect the hose assembly from the condenser.
- Remove the O-ring seal from the condenser hose.
- Cap or plug all of the open connections.
Installation Procedure
- Coat the new O-ring seal with 525 viscosity refrigerant oil.
- Install the new O-ring seal to the condenser hose.
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.
