Why is my serpentine belt coming off? It's come off twice in a day when I take a freeway cloverleaf. It never did this before. I hear a little noise from the power steering pump. The first time it wrecked my belt. I bought a new belt and the first clover leaf I took it came off. I checked the fluid in my power steering resevoir and it was nearly full.
What gives?

Do you have an underdrive pulley by chance? Either way I would replace the tensioner, but if you have an underdrive pulley, check out Thunder Racing for a billet Katech adjustable one, you'll need it then.

Just buy the Katech pulley or get the Larry pulley. The tensioner was a horrible design by GM, no need for tension on any pulley. Depending on how much power you have a good pulley will not hold the belt. I tried two brand new ones and it didn't matter, when I wacked the throttle and checked it it was halfway off each time. One more hit and it might have come off. Luckily I noticed it one day when I checked my oil. Got the Katech pulley and it hasen't budged since, it simply can't.

It came off again tonight going through a tunnel on the freeway. 
I was just cruising at 65mph. I couldn't go back and get it. There's $25 down the drain.

To throw a belt at a steady cruise you have a BAD tensioner, or it was almost off to begin with from earlier in the day and finally worked its way off.
I think it was $139.00 or something like that, can't remember.
