Important: Keep dirt and foreign material from getting on the sealing surfaces of the following components when removing the 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.

1. Disconnect the negative battery cable.
2. Discharge and recover the refrigerant from the system. Refer to Refrigerant Recovery and Recharging .



3. Remove the following components from the A/C compressor:

•	The A/C compressor hose block fitting bolt

•	The A/C compressor sealing washers

•	The refrigerant hoses

•	Discard the A/C compressor sealing washers.




4. Remove the refrigerant hose from the A/C condenser.
5. Remove the O-ring seal.

Discard the O-ring seal.




6. Remove the refrigerant hose from the A/C evaporator.
7. Remove the O-ring seal.

Discard the O-ring seal.

8. Remove the following items from the hose attachment points:

•	The hose clamp nuts

•	The washers

•

The bolts

•	The hose clamps

Important: 

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.

1. Install the hose clamps to the refrigerant hoses and the hose attachment points with the following items:

•

The bolts

•	The washers

•

The nuts

Tighten
Tighten the refrigerant hose clamp nuts to 17 N·m (13 lb ft).

2. Coat the new O-ring seal with 525 viscosity refrigerant oil.
3. Install the new O-ring seal in the A/C evaporator end of the refrigerant hose.
4. Install the refrigerant hose to the A/C evaporator.

Tighten
Tighten the refrigerant hose fitting at the A/C evaporator to 32 N·m (24 lb ft).




5. Coat the new O-ring seal with 525 viscosity refrigerant oil.
6. Install the new O-ring seal in the A/C condenser end of the refrigerant hose.



7. Install the refrigerant hose to the A/C condenser.

Tighten
Tighten the refrigerant hose fitting at the A/C condenser to 23 N·m (17 lb ft).

8. Fill the refrigerant hoses. Refer to Refrigerant Oil Distribution Specifications .
9. Install the new sealing washers onto the pilots of the block fitting.

Bottom the washers against the surface of the block fitting.

10. Install the refrigerant hoses on the A/C compressor with the A/C compressor hose block fitting bolt.

Important: There should be a 1.2 mm (0.047 in) space between the block fitting and the A/C compressor rear head.

11. Hold the block in place.

Hand tighten the A/C compressor block fitting bolt.

Tighten
Tighten the A/C compressor hose block fitting bolt to 35 N·m (26 lb ft).

12. Connect the negative battery cable.
13. Add the refrigerant to the system. Refer to Refrigerant Recovery and Recharging .
14. Inspect the system for leaks. Refer to Leak Testing .
