This is a custom designed wrench developed by Tools R Us (Kevin) for the 1FZ SuperCharged engines. This tool is a MUST when changing out or just removing the SuperCharger's serpentine belt by relaxing the tensioner pulley.

I have been dreaming of finding one of these for years! Trying to rig up socket wrenches and box end wrenches to loosen the belts on my supercharger is just silly. Now, with this wrench it's a breeze
Worth every penny. Changing the supercharger belt or pulley without this tool is a nightmare. with this tool it’s breeze. Thank you Wits End for producing this. Makes life much easier.
