(3) - Pulleys

​It is recommended that you have an additional person available to help during this installation, parts can be awkward to hold and support by yourself. Block wheels and set parking brake before beginning work.

With the belt still attached, loosen the 15/16” nut in the center of the alternator pulley. Leave the nut loose, but in place.

Loosen the (4) 1/2” water pump / cooling fan bolts.

Loosen the (4) 9/16” crank pulley bolts in the crank pulley.

Attach a 3/8” socket extension to the square hole in the idler pulley and turn counter clockwise until the tensioner stops and the belt can be removed from all pulleys. Remove all hardware that was previously loosened.

Remove all 3 stock pulleys, by pulling them toward the front of the car and replace them with the 3 aftermarket pulleys. Make sure the crank pulley has the shallow side facing the engine and the deep side facing the radiator.

​Tighten all hardware. Reinstall the stock belt.
