My 99 suburban has started to squeel upon start up. It goes away after about 15 minutes. I've replaced the idler pulleys, alternator, belt etc. I'm thinking it's the fan clutch or the a/c but I would like some opinions before I replace either.
What are your thoughts?
Anyone else experience this?
Thanks for any help,
Mike

 

Is your idler pulley adjustable?

 

Did they ask you for the amperage of the alternator when bought the belt? There are 2 belt sizes available. If you have the large of the 2 try the smaller one. Does the noise go away when you spray water on the belt?

 

I recently ran into that with a 97 Tahoe, 1 belt is about 1/2 inch longer than the other.

 

I don't believe the idler pulley is adjustable.
The noise "does" go away if I spray water on it.
Mudmaniac, so yours was the wrong belt?
Is my belt too short or long?
Thanks for the help on this one.

 

From what you have described, the belt you have would be a little to long causing it to be loose.

 

Thanks MM I'll go get another belt and see what happens.
