Removal Procedure
Important: Keep dirt and foreign material from getting on the sealing surfaces
of the following components when removing the sealing washers:
• The washers • The block fitting • The air conditioning (A/C) compressor ports
- Disconnect the negative battery cable.
- Discharge and recover the refrigerant from the system. Refer to Refrigerant Recovery and Recharging .
- Remove the following items from the A/C compressor:
- Discard the A/C compressor sealing washers.
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.

Installation Procedure
Important:
• Keep dirt and foreign material from getting on the following sealing
surfaces when installing the sealing washers: - The washers - The block fitting - The A/C compressor ports - Clean all sealing surfaces with a lint-free rag. • Do not reuse the sealing washers. • Do not oil the sealing washers prior to assembly.
- Install the new sealing washers onto the pilots of the block fitting. Bottom out the washers against the surface of the block fitting.
- Install the A/C compressor hoses on the A/C compressor with the A/C compressor hose block fitting bolt.
- Hold the block in place. Hand tighten the A/C compressor block fitting bolt.
- Connect the negative battery cable.
- Install the refrigerant to the system. Refer to Refrigerant Recovery and Recharging .
- Inspect the system for leaks. Refer to Leak Testing .
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.
Important: Verify that there is a 1.2 mm (0.047 in) space between the block fitting and the A/C compressor rear head.
Tighten
Tighten the A/C compressor hose block fitting bolt to 35 N·m
(26 lb ft).
