Not too long ago, I had a problem with my serpentine belt slipping halfway off the tensioner pulley. I bought a new belt and I thought it was fine again.

Then just last night, I was messing around with a turbo VW on the highway. I downshifted to 3rd and nailed it, when a few seconds later I noticed my power steering was gone and my check gauges light came on. Sure enough, the belt flew right off.

How should I troubleshoot this? Should I replace the tensioner? the idler pulley? I also have heard about the "larry" pulley that has a lip. Which pulley does this replace and where can i buy one?

I'm having the same problem but I haven't replaced anything yet. The 'Larry' pulley is currently out-of-stock. I didn't order one yet. I think the cost is ~$50, I didn't jot that down.

You can get it at ASPRacing.com

I HAD the same problem. After installing a new tensioner pulley with higher ridges it never happened again. I guess I have the "larry pulley"?!?! I bought the pulley only and it is from ASP. I ordered from Thunder Racing.

Yea, the "Larry" pulley will fix it.

You need the Larry pulley or something like it.

I bought it direct and it was expensive.

I called ASP direct and they are out of them for about a week. This damn thing costs $65

Compare that $65 to buying a new belt at $35 a pop (mine was torn to shreds every time mine flew off), and possibly needing your car towed if you lose the belt all together... Plus, imagine being stuck on the side of the road as the rice boys pass you by laughing at your "unreliable" LS1 !!!

Does anybody have the part number for the "larry" pulley. I can't find it on the ASP site.

Need to call ASP. It's a "special" part.
