Pulley replacement - P1SC
 

Does the head-unit P1SC have to come off the car to replace the pulley? Can it be removed/replaced while on its engine mounts? I'm thinking of changing from the 8# to a 12# pulley.

Plan on removing the head unit for installation. It not too tough.

Tip, use an impact for pulley bolt removal/installtion and Loctite 262 on the threads. If the pulley is stuck you can use heat from a propane torch on the pulley to help it off. Don't direct heat towards the seal.

Torque needs to be about 65/70 ft/lbs or about what you'd put on a lug nut.
