I got the idea of posting this after reading one of Blacktibs' posts in his topic about engine repairs. I noticed that he was talking about the belt squealing, even after they were brand new and tightened properly. I've been having this same problem.. and I can't figure it out. The belts were JUST swapped maybe 500 miles ago.. and they've started squealing AGAIN. They squealed before, so I generally assumed they were getting worn out, as I was approaching the 60k mile mark. So I had them all changed, but they're squealing again? I lubed 'em up with some belt dressing.. and it keeps them quiet for a while, but then the squealing starts back up, and constantly squeals until it gets a little warmer.. not sure what to do.. any suggestions?

after 500 miles you may need to retighten belts.

autozone has "quiet belts"

supercow

yeah retighten them. that will fix it.

They're squealing because they're slipping, and your new belts are probably ruined if they've been doing it regularly. It's a good way to kill the pulley bearings as well, since constantly-slipping belts generate a lot of heat. I should know, unfortunately I recently had firsthand experience.

Don't use belt dressing. The real fix is to sand the glazing off the pulleys BEFORE you put on new belts. I used scotchbrite pads on mine, and thoroughly cleaned them with brake cleaner. You can run the belts tighter to prevent slippage, but that's not a good fix.

how do you tighten them?

Dmitry

what pulleys do you have?
stock or aftermarket?

Dmitry I didn't know if you were talking to me or replying to kcvortex's post right above yours so I decided to answer.. I have stock pulleys right now.

Dmitry

my belts squeel alittle bit at idle when I turn the wheel but only when it's really cold. I too have stock belts that were just replaced like 6000 miles ago.
