i just got done putting my car back together. i have had every possible problem but i finally got them all fixed and figured out and now my belts squeel like crazy at about 2500-3k and the more u give it the louder it gets! its drivin me crazy. i cleaned the pulleys with an all purpose cleaner and a nice clean dry rag. all the pulleys line up (had that problem already) and they are good and tight. used a big pry bar to pry them tight and tighten then down. it almost sounds like my fan is hitting something but its not. and i only have 2 belts, power steering and water pump/alternator. alternator is new so dont think i have a bad bearing. i dont know what to do but im goin nuts. and ideas?

 

Probably not enough belt surface contact. I used to have the same problem so made the switch to an electric fan

 

you might have them too tight or loose you might even have to replace the older one

 

i'd replace them all and see if that fixes it. unless you just bought them it wouldn't hurt changing belts.
