Just finished the PSK install to clean up a noisy idler pulley and WOW..she is so much quieter and smoother now I might be imagining it, but the torque feels a little better too. Here's a couple pics to clarify what the initial post above was referring to on the tensioner: just hold the torx screw in place while you loosen the nut holding the pulley. The pic of the emissions tube shows the screw you need to undo to give play in the tubing in order to slide the belt off the SC pulley. Did anyone find that the screw included to hold the tubing clamp in place was dangerously close to the belt once tightened down on the bracket?
