i have a bad squealing coming from the serpentine belt on my truck. i just replaced it a month ago and it has been doing it ever since. i tried putting some belt dressing on there hoping it would cut out on the squealing but it seems to just get worse and worse. i really don't have the money right now to take it to a shop. is there anything i can do to fix it?

Which engine? The 2.5L I4, 3.0L V6, or 4.0L V6? Are you sure it's a belt or accessory drive problem? Try removing the belt first then, start the engine and see if you still hear the sqeeling noise. If the noise disappears, shut the engine off and spin the alternator, water pump pulley, tensioner pulley, and idler pulley by hand. Whichever one "feels" abnormal should be the culprit. If the noise still persists, even with the belt removed, you've eliminated everything the belt drives as the source of the noise, including the belt itself, and need to look elsewhere for the cause of the noise. Hope this helped.

Not sure what the answer is because I'm looking for it as well. I have a '92 Ford E150 full conversion van 302cid (5.0L) that sometimes squeals so bad my wife and kids want to hide their faces when we drive down the street. To those of you who think it's 'moisture': WRONG! I've tried bar soap, glue stick, WD40, belt dressing (not recommended for serpentines (which I have)) and cursing; none of them work. I've replaced numerous belts over the years and I've replaced the belt tensioner. Somewhere I read in one of the threads (I believe it was from a Ford pickup owner) that it is the fan clutch; that if the clutch is going bad, the belt will drag across the pulley when it's not free-wheeling. We've used strobe lights and checked the alignment of all the pulleys, still no clue. Could this be another Ford system-laden anomaly? Looking for answers in Heidelberg, Germany! JP...

are you sure it is the belt , and not either the tension pulley or the idler pulley ( the stationary pulley located at the top that the belt runs on ) mine was making a noise (( squealing )) I replaced the idler pulley ,and it was fine ....check all of your pulleys , a new belt has a little more tension that an older belt . unless you are 100% sure it is the belt I would do that .

Take off the belt, and use some 320 grit sandpaper on all of the pulleys, then put on another new belt. If this doesn't help, you may have a bad idler pulley, which are easy to change.

Couple of possibilities. Try spraying the belt with wd-40. If the squeak comes back, then with the engine running, carefully scuff the side of the belt with the ribs with a wire brush.
Moisture usually causes the squeaking. You may have a leaky hose or water pump. Look carefully.
Good Luck

you probably have an idler pulley spuealing. take a long screwdriver and carefully put the tool end on the pulley while it is spinning..put your ear on the other end.....test each idler until you find the one that is grinding/squealing....replace the pulley and put the belt back on....prob solved.

I am sorry I have ford Ranger also, ran into the same problem. What I found out as mentioned by a earlier respondant was a leaky intake gasket apperantly ford does not believe in tighting there bolts since my intake was loose.

if the problem is your idler pulley you can replace just the bearing in the pulley. usually just a few dollars. it could be a problem with any of the driven pulleys though. alternator, power steering, air cond. or water pump. but i would check the idler pulley first. common on ford
