will the 03-04 cobra tensioner work for the 01 cobra?
no it is from the dealership.and yes it is a single bolt tensioner with a 8 rib set up.the spring it self can't handle the power for some reason.i just ordered another one so hopefully it will last longer then 2months this time.No, it won't. The 01's have a single bolt tensioner.
What part of the tensioner is going bad? Is it the pulley itself or the spring inside the tensioner? Did you use a Ford part or did you pick one up at the local parts place?
