Removing the A/C compressor clutch begins with disconnecting the battery negative cable, uncovering the serpentine
Drive Belt and unplugging the compressor clutch coil wire harness connector. After that, lower the bolts securing the compressor to its bracket, slide out the compressor and support it in your engine compartment. Put a spanner wrench (Special Tool C-4489 or its equivalent) on the clutch plate to hold it in place and as you do this, remove the hexnut that connects the plates. Place snap ring pliers on the snap ring to unfasten it and then press the lip of the rotor puller (Special Tool C-6141-1 or its equivalent) into the groove of the removed ring. Place a shaft protector (Special Tool C-6141-2 or its equivalent) at the other end of the rotor. Secure the puller with bolts, C-6461 or comparable and turn the center bolt clockwise in the center until you can free the rotor, while making sure not to touch the end of the compressor. Removed the screw and retainer from the clutch coil lead wire harness, slide the snap ring off the compressor hub, then lift off the clutch field coil. Check the clutch rotor and plate for signs of wear and return them for replacement if there are many scratches. Check for oil in the shaft area; if the cover felt is moist, the shaft seal is gone and the compressor must be changed. See if the rotor bearing is rough or is dripping too much grease; if that's the case, replace both the rotor and clutch plate. Begin installation by setting the clutch field coil and snap ring in place and then attach the clutch coil lead wire harness using the 2.2 Nm (20 in. lbs.) tightened screw. Attach the rotor assembly to the hub of the front compressor with the hollow to the outside and fit it into the bearing with Special Tool C-6871. Make sure the bevel of the front housing snap ring faces outside and fully push it in place, so the clutch won't fail. Install the original shims on the compressor shaft, then put the clutch plate on and tighten the shaft hex nut to 15 - 20 Nm (11 - 15 ft. lbs.). In addition, use a feeler gauge to see if the clutch air gap is between 0.41 and 0.79 millimeters (0.016 and 0.031 inches) and add or subtract shims as necessary.
