You know how some cars make a really high pitched squealing noise when it's really cold? Something to do with the alternator or belt, I usually hear, but anywho it started with my car a little back and I figured it was just something cold related and that it would go away.

Well it never did, and after taking a look it would seem that my timing belt cover could be rubbing against the serpentine belt (97 2.0l sohc). When I push against the raised portion of the timing belt cover the noise goes away. Everything looks nice and tight though, no loose bolts or screws, so what should I look for/try to do here to stop making my car the noisiest bastard on the block?

Most likely its the serpentine belt tensioner. Replace that and put on a good quality belt (like a Goodyear Razorback but thats just one of many quality ones) and the noise should go away. - Peter

You could try sanding down the part of the timing cover that is rubbing. Since it's plastic it will be easy.
