Squeaking belt

showcrop · Jun 8, 2014

The serpentine belt on my Ford 8240 squeaks loudly. It goes away temporarily when I spray water on it so I know that it is not one of the pulleys. I have spent a lot of time getting it perfectly aligned but it still squeaks badly except when I throttle down after working for awhile. Could it be the belt itself?

Could be your serpentine belt tensioner is stuck, and not giving the
correct tension to the belt...

I've never had a serpentine belt squeal but I've had regular fan belts squeal so bad they'd send chills up my X wifes spine & then I had troubles . My Dad always used a large bar of moistened Ivory soap on them . A dry bar wouldn't let the soap stick so it had to be moistened before applying it . I found a spray belt lubricant at an auto parts store once wnich didn't seem to work as well as the Ivory soap did . HTH ! God bless, Ken

It most likely is the belt. That would be the
easiest and cheapest first try.

Sounds like you've already checked the obvious,
alignment and tension. But take a look at the
pulleys, especially the crank pulley and the
alternator. Be sure they aren't worn. It takes a
careful inspection, the ribs of the new belt should
not bottom out between the ribs of the pulley.

I had one on my '91 Ford Ranger that squeaked till it almost drove me nuts. Replaced the belt with a new "Gates" brand and haven't had a squeak since.

I heard a belt noise one time that I thought was the power steering pump:it was a neighbor's car and I told him to change the pump. He did and still had the noise, so he changed it again. Turned out to be the belt! Moral:change belt first. Mark

The belt on the bale loader did that. We always used the bar of
soap trick. We didn't use ivory - we used the free ones from a
hotel.

Bees Wax is a belt's best friend..

Will help them last a longer time and seems to eliminate squeal..water-proof, too..

Your belt is glazed or tenioner spring is soft or stuck.Also make sure you have right length belt.

My 93 ford pu has done that a lot. The only thing that will fix it is a new belt. I put 3 of them on so far. It is worse in damp weather also.
