    Greetings all. Happy New Year.

    The idler pulley on my '02 GTP broke today, so I picked up a new pulley and both belts.

    I am thinking about replacing both the supercharger and accessory tensioner assemblies as well. I do not have a service manual and cannot tell is there is an accessory belt idler pulley, but if I can see one tomorrow in the daylight, I will replace it also.

    But first, did I purchase the correct supercharger idler pulley? I bought the grooved Gates p/n # 38009. The remains of the pulley that broke is no where to be seen, so I don't know if I need the grooved or non-grooved part. Did I get the right one?

    As for the tensioner assemblies, it looks like Gates p/n # 38365 for the supercharger and p/n # 38271 for the accessory belt.

    The installation of the supercharger assembly looks pretty straight forward, other than maybe needing a special tool.

    The accessory belt assembly looks a little more troublesome. From the pics it looks like it may serve more than one purpose. If so, what else does it do? What are the two 90 degree fittings for? Wondering if I may be opening up a can of worms here. You know, working in my driveway in the winter.

    Is there an idler pulley for the accessory belt?

    And do I need any special tools?

    Any suggestions or tips will be greatly appreciated.

    Thank you,

    Scott
