New ASP idler pulley and install pic.
Thanks.

So far I've picked up the following from the dealership:
Serpentine belt tensioner - 1122000970
supercharger belt tensioner - 1132000170
idler pulley - 1132020419
I think I'm going to return the idler pulley, and purchase both idler pulleys from ASP.
MY QUESTION:
Does anyone know what the correct torque specs are for each part?
torque spec of each idler pulley?
torque spec s/c belt tensioner bolts?
torque specs of serpentine belt tensioner bolts?
Thanks a lot for these write ups. They are very helpful.
