93 Shadow squeeking belt

Hey all, I got a 93 Dodge Shadow converteble with a 2.5L automatic 3 speed. The problem is the serpentine belt squeeks and I can't get it to stop. I have replaced the belt, checked the alternator bearings, the water pump does not leak. I know it's this belt cause, I have taken it off and the squeek stops (and I replaced the other belts too.). Does anybody have any ideas on how to quiet it up. I am at my wits end. I have tried all that I know. Any and all help will be greatly appreciated.

is it tight?
I do remember seeing a belt lubrication somewhere.. maybe that would help...but hopfully it wouldnt slip off.

There must be a way you can tighten it. Is it a real serpentine that just has a tensioner or is it a vee belt where you can tighten it from the alternator or a/c pump or somewhere?

Yeah it's tight. It does run around a tensioner, but like I said all is tight and running true (as far as I can tell).

Parts stores sell spray cans of "Belt Dressing". That's a substance that's a bit tacky and you spray it on the belt and the pulleys. Stops the belt from slipping.

hadthe same problem thought was my alternator beraing turnes out to be the belt... i buaght a replacemtn a cheap one and it still squeeked.. finally i spent the money and baught a little bit more expensive belt and no more squeeking. ... also one again make sure you belt it tight. or not over tightened

Thanks all for your responses. I fixed it, it was the rubber bushings in the upper mounting bracket. They were worn out and out of alignment. I replaced both of them and checked to make sure it was all in a straight line ( had to shim one of them ). All is good now. thanks again all.
