Question about 1997 Chevrolet Cavalier

Tension pully is loose making the belt rattle

I changed the broken surpintine belt. Went to drive off and I hear this rattling, (the same sound I heard before the first belt broke)
So when I look I see the belt very loose in one spot. (the tension pully moving alot).
Is this a loose part or a broken part?
Thanks in advance for any help.

It sounds like you have a broken serpentine belt tensioner. The tensioner should always be tight, it is spring loaded and you would have had to release the tension on it to have put the new belt on.Depending on what engine that is in yours, this could be an easy fix or a hard fix. The tensioner on a 2.2L is made into a large plate bracket that is attached to the front on the engine and several other items have to come off to replace it.The tensioner on the 3.1L v6 is smaller and has one bolt that holds it on.Either one is available at the local auto parts store.

Hope this helps

Obviously one of the pulleys is loose or the tensioner is faulty.
I would check all of the pulleys before trying to put the belt back on.
You should find a bad bearing or broken spring.

You broke your serpatine belt. Needs replacing. It's a $50ish part and easy to do if you have a diagram under the hood of how the belt fits. But if it was "rattling" for a couple of weeks take it in for crying out loud. Let the mechanic look it over to make sure your lack of vechile care didn't destroy anything under the hood.....

I have a rattling sound up towards my belts. kinda sonds like a ceased barring. near my alternator


The best way to find the noise is to remove the belt
and check each pully by hand. If a pully locks up it
will make more of a screeching sound. A rattle sound makes me think your idler pully is loose.
Hope this helps. Good luck.
