Remove the serpentine belt to gain access to the air conditioner belt and clutch. Locate the tensioner pulley on the serpentine belt. Put the appropriate size wrench on the nut in the center and rotate it until the pressure is released, usually clockwise. Remove the serpentine belt. Loosen the tension adjustment on the air conditioner until the belt slides off of the pulley, and remove it.

Unplug the electrical connector to the compressor coil. Remove the bolt in the center of the AC clutch, slide the clutch off of the shaft, and lift it out of the engine compartment. There are spacers on the shaft which are necessary to gap the clutch properly. Slide them off, keep them in a safe place, and thoroughly clean the shaft. Remove the snap ring that secures the pulley, and slide it off of the clutch shaft.

Snap-ring the pulley into place on the new clutch with the bevel side out. Put one spacer on the shaft, and slide the clutch on. Use the feeler gauge to check for the proper clearance, and add another spacer if it is not correct. Reinstall the AC belt, plug in the electrical, and install the serpentine belt.
