belt tensioner replacment

I bought a new belt tensioner for my 97 GTP, I was just wondering if anyone has changed one before, and if there is anything special that I need to look for or do. Thanks any input will help.

Two 13/15mm bolts (can't remember which)..that you will turn counterclockwise to take it off..first you need to take off the belt..and use a 15mm wrench and turn it towards the firewall..if you go the other way you will be replacing the tensioner...take off the two nuts on the tensioner and go from there..install is just the opposite..cya Mik

I did my S.C. belt tensioner this last weekend, wasn't too bad. The only thing that slowed me down was holding the belt so I could thread it around all the pulleys, etc.
