For 1990-2009 cars

### Removal Procedure

1. If the vehicle is equipped with power steering, refer to Power Steering Pump Replacement in Power Steering for the following removal procedures:

• | The power steering pump

• | The mounting bracket

2. Disconnect the compressor clutch electrical connector (6).
3. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
4. Remove the engine splash shield. Refer to Engine Splash Shield Replacement in Body Front End.
5. Loosen the idler pulley locknut (4).
6. Loosen the idler pulley adjusting bolt (1).
7. Remove the compressor drive belt (2) from the clutch pulley.
8. Remove the 3 bolts (1,4,5) from the compressor.
9. Set the compressor aside.
10. Remove the 4 bolts (3,4,5) and the compressor mounting bracket from the vehicle.

### Installation Procedure

1. Install the compressor mounting bracket to the engine block.

Important: The correct torque sequence is essential in order to prevent damage to the engine block or to the compressor bracket.

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.

2. Secure the compressor bracket with 4 bolts. Tighten the bolts in the following sequence:

2.1. | The bolt (4)

2.2. | The bolt (5)

2.3. | The bolt (3)

3. Tighten the bolts.

Tighten
Tighten the compressor bracket bolts to 34.3-39.2 N·m (25.2-28.8 lb ft).

Important: The correct torque sequence is essential in order to prevent damage to the compressor or to the compressor bracket.

4. Install the compressor to the compressor bracket.
5. Secure the compressor with 3 bolts (1,4,5). Tighten the bolts in the following sequence:

5.1. | The bolt (4)

5.2. | The bolt (5)

5.3. | The bolt (1)

6. Tighten the bolts.

Tighten
Tighten the compressor bolts to 22.5-27.4 N·m (16.5-20.1 lb ft).

7. Install the compressor drive belt (2).
8. Verify that the belt is correctly aligned on the compressor, on the power steering, and on the crankshaft pulleys.
9. Adjust the drive belt tension.

9.1. | Turn the idler pulley adjusting bolt (1) in order to obtain belt deflection that measures 7-9 mm (0.28-0.35 in) at 10 kg (22 lb) of force.

9.2. | Tighten the idler pulley locknut (4).

Tighten
Tighten the idler pulley locknut to 44.1-49 N·m (32.4-36 lb ft).

10. Connect the compressor clutch electrical connector (6).
11. Secure the electrical connector wire with the clamps (5).
12. Install the engine splash shield. Refer to Engine Splash Shield Replacement in Body Front End.
13. Lower the vehicle.
14. Install the power steering pump and the bracket, if removed, Refer Power Steering Pump Replacement to in Power Steering.
