Question- Replaced the waterpump today on my '01 TJ 4.0. Went to put the serp belt back on, and it was really loose. Huh? I grabbed the tensioner and it was "sprung" all the way in as far as it would go. Thinking hmm, the belt must have stretched three or four inches since I took it off, I bought a new belt, and what do you know, it's also too loose. It's loose enough to squawk off idle or when the lights or AC is on. What is going on here? Is there a way to "re-set" the tensioner? It has some marks on it and a little pin coming out the side but I'm not sure what it means. The Haynes is completely useless in this regard. (the pics are for a V-belt setup!)

I need a solution ASAP as this is my daily. <img src="/forums/images/graemlins/scared.gif" alt="" />

Thanks!
