Hi, On my 93 Geo Tracker on start up I get a high pitch squeal. Shut it off and restart and it usually goes away. I have changed out the belts with goodyear gatorbacks, the timing belt and tensioner, water pump, alternator, power steering pump, the only thing original is the a/c condenser. I have tried the belts loose, tight and in between. After starting several times you can drive it all you want and it will never squeal. It just does it on cold starts. Oh, I have even tried that junk belt dressing stuff. I'm really at a lost here, not only can't I seem to fix it but its really embarrassing in public.  Thanks for any help!!

Check the "alignment" of the pulleys.

A squeal after a cold start is usually a belt slipping under the load of the alternator, but it's not always a slack belt, it can be glazed pulleys (crank or alternator), and it can also be one of the pulleys out of alignment - I had a similar issue, replacing the belt would solve it for a few months, and after it returned with the second replacement I started hunting for other causes, in my case one of the alternator pivot bolts was missing, allowing the alternator to tilt just enough to rub the edge of the belt.

Another place to check is the intake manifold "gaskets" - make sure the bolts are tight where the manifold bolts to the head, and where the throttle body bolts to the manifold - an air leak will sometimes squeal and sound like a slipping belt - I don't think this is likely to be the problem, especially on a fuel injected engine, but you never know.

Thanks Fordem for your reply, I appreciate it. I'll check those things!
