Sub-Procedure
Removal
1. Remove the bolt while holding the armature plate with the A/C clutch holder.
NOTE:- Do not pry on the armature plate with screwdrivers or similar tools. Prying damages the armature plate and the pulley.
- Inspect the armature plate and pulley friction surfaces for wear. If there is excessive wear, roughness, or scoring, replace the clutch set.
- If traces of refrigerant oil is found around the compressor, replace the A/C compressor - Refer to: A/C Compressor/Engine Oil Pan Area(3.0L Engine) or A/C Compressor/Engine Oil Pan Area(2.0L Engine) .
Installation
- If the A/C compressor clutch surface is oil soaked, check the A/C compressor front seal for leakage. Installing a new A/C compressor clutch assembly on a leaking A/C compressor will damage the new A/C compressor clutch assembly friction surfaces. If excess oil is present and it is not from the engine or other system, replace the A/C compressor - Refer to: A/C Compressor/Engine Oil Pan Area(3.0L Engine) or A/C Compressor/Engine Oil Pan Area(2.0L Engine) .
- Clean the pulley and the A/C compressor friction surfaces with contact cleaner or other non-petroleum solvent.
After Installation
- Cycle the A/C compressor clutch approximately 20 times by running the engine at under 2, 000 rpm for 1 minute or more and setting the A/C system to ON. This procedure seats the A/C compressor clutch sliding surfaces, and increases clutch torque capacity.

Sub-Procedure
Removal
1. Remove the snap ring (a) with the snap ring pliers. (Figure 1)
Figure 1
2. Remove the A/C compressor pulley (b) with the puller. (Figure 2)
NOTE:- Do not hammer or pry on the pulley to remove it. Using a hammer damages the A/C compressor. If the pulley is difficult to remove, use a commercially available pulley removing tool. Make sure the jaws of the pulling tool engage the back face of the pulley, not the pulley grooves.
- Be careful not to damage the pulley or the A/C compressor.
Figure 2
Installation
- Clean the pulley and the A/C compressor friction surfaces with contact cleaner or other non-petroleum solvent.
- Install the snap ring as shown, note the installation direction, and make sure it is fully seated in the groove. (Figure 3)
- Make sure that the pulley turns smoothly after it is reassembled.

Sub-Procedure
Removal
- Remove the snap ring (a) with the snap ring pliers. (Figure 1)NOTE:
Inspect the friction surfaces and the compressor shaft hub for excess oil. If excess oil is present, and it is not from the engine, then the compressor shaft seal is leaking. Replace the A/C compressor - Refer to: A/C Compressor/Engine Oil Pan Area(3.0L Engine) or A/C Compressor/Engine Oil Pan Area(2.0L Engine) .
Figure 1
Installation
- When replacing the field coil, check that the new coil has the correct resistance .
- Align the boss on the field coil with the hole in the A/C compressor. (Figure 2)
- Install the snap ring as shown, note the installation direction, and make sure it is fully seated in the groove. (Figure 3)
