3. Remove the cross vehicle brace. Refer to Cross Vehicle Brace Replacement in Body Front End.
4. Remove the accessory drive belt. Refer to Drive Belt Replacement in Engine Mechanical-3.1L.
5. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
6. Remove the lower air deflector. 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 the A/C compressor.
10. Disconnect the electrical connector from the A/C compressor.
11. Remove and discard the sealing washers.



12. Remove the lower A/C compressor mounting bolts.
13. Remove the upper 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: Replacement A/C compressors are shipped without oil. Refer to Refrigerant System Capacities for A/C 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.

8. Install the right side engine splash shield. Refer to Engine Splash Shield Replacement in Body Front End.
9. Lower the vehicle.
10. Install the accessory drive belt. Refer to Drive Belt Replacement in Engine Mechanical-3.1L.
11. Install the cross vehicle brace. Refer to Cross Vehicle Brace Replacement in Body Front End.
12. Install the right front diagonal brace. Refer to Front Fender Upper Diagonal Brace Replacement in Body Front End.
13. Evacuate and recharge the A/C system. Refer to Refrigerant Recovery and Recharging .
14. Leak test the fittings of the component using J 39400-A .
