Squeak at Startup

Lately when starting "cold," (l live in Florida, temps get down to about 60 at night) I have been hearing a slight chirp for the first few minutes when running. Occurs with A/C on or off, no increase chirp with rpm (that I could hear), and about 3 months ago I replaced a frozen tensioner and an alternator with bad bearings that was causing the same kind of sound. Is it definitely the idler pulley?

It is likely, you can take the idler pully off, pop the bearing out, take it to the parts store and get a replacement for about $8 or so. It was the belt on my 96 obs causing the chirp.

Don't forget the belt...

I thought my tensioner was making noise so I replaced it only to discover it the noise wasn't coming from any pulleys or the tensioner...

It was coming from the belt.

I just replaced it yesterday and the squeak is gone.

I'd recommend doing it with a buddy though, so one person can route the belt up top and the other person can be under the truck to route them onto the lower wheels.

Good Luck!

Thanks for the quick replies! However I don't think it is the belt because after replacing my tensioner the noise stopped for about 3 months. It just recently started this week.

Then it is most certainly the belt.

The new tensioner was able to tighten the belt back up for 3 months, but the belt was still wearing out.

It has now tighten as much as it can with the worn belt.

My belt looked new with no crack or signs of wear, but it was streched out.

It's a $52 belt at Napa...
