Just in time
Heard my tensioner squealing early in the week, so I ordered it. The part came in on the day my tensioner seized and broke the pulley. Removed and replace in about 30 mins. Part came in just in time.

what is the size of the center Torx screw?
Ash N July 31, 2018
I dont have the exact measurements of the part or the screw. Our parts are designed to be exact replacements for what came with the vehicle, so as long as your year, make, and model match up with our listing, these will definitely fit and function just like the original. Please let us know if you have any other questions.
