I have gone through two belts In the past couple of hours I replaced the first one and drove for about 10 minutes before it tore again...

It was making a very loud squeaking noise the entire time I drove.

I noticed this ?pulley? is not moving when the car is on and it seems to be the problem

any input will be highly appreciated.

Thanks!

By the way the car is a 1992 Rs Stock 305

 

That's the tensioner idler pulley, should spin very freely. if it is locked up, you can buy a new one at any auto parts store for 20.00 or less, one bolt in the middle holds it on. I just replaced mine a couple of weeks ago. the new one won't have the raised edge, just a flat pulley, will work fine.

 

That did the trick. Thanks!
