2. Remove the right sheet metal diagonal brace. Refer to Front End Sheet Metal Diagonal Brace Replacement in Body Front End.
3. Remove the generator. Refer to Generator Replacement in Engine Electrical.

Important: The A/C compressor is accessed through the right wheel opening.

4. Turn the steering wheel to the right before lifting the vehicle.
5. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
6. Remove the lower radiator air baffle. Refer to Radiator Air Baffle Assemblies and Deflectors in Engine Cooling.
7. Remove the right side engine splash shield. Refer to Engine Splash Shield Replacement in Body Front End.
8. Remove the A/C compressor hose bolt.
9. Disconnect the A/C compressor hose from A/C compressor.



10. Disconnect the electrical connector from the A/C compressor.
11. Remove and discard the sealing washers.



12. Remove the front and rear A/C compressor mounting bolts.
13. Remove the top A/C compressor mounting bolts.
14. Remove the A/C compressor.
15. If replacing the A/C compressor, drain and measure as much of the PAG oil as possible from the removed A/C compressor:

•	Drain the PAG oil from both the suction and discharge ports of the removed A/C compressor into a clean container.

•	Rotate the A/C compressor crankshaft to assist draining the crankcase oil.

•	Measure and record the amount of PAG oil drained from the removed A/C compressor.

•	This measurement will be used during installation of the replacement A/C compressor.

Important: The replacement compressor is shipped without oil. Refer to Refrigerant System Capacities for compressor oil capacity.

1. Install the A/C compressor.

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.
