I have a 2002 lx that i recently replaced the alternator and the serpentine belt on. It now makes a slightly noticable squeal under acceleration about 2 weeks later. Could anybody maybe send me in a direction of what would make the slight squeal? I don't want to break anything lol. Any help appreciated. Thanks

 

When you install the belt you're supposed to run the car 5 minutes then re-tighten. I suggest you try to re-tighten the belt.
