Belt/Pulley Squeaks? (2006 Ford Taurus)

oh yah have your harmonic balancer cheched because you can change every thing but if the balan. gets out of wack it un alines everything

Pulley alignment is the next place to look, DO NOT USE BELT lube, makes it worse.This presumes that each and every pulley turns easily.....

That all depends on when and where it squeaks. If it starts squeaking as soon as you start it there is a good chance that you have either a bad belt or a bad pulley. If it squeaks only when the vehicle is moving then there is a good chance you have a wheel bearing going out. I hope this helps you out, and if you have any more questions please feel free to ask.

Belts squeak for the same reason tires do when they spin. They are slipping. Something isn't turning as fast as the belt wants it to. On ford it's usually ether the idler sprocket or the tensioner. If you remove the belt and try spinning all of the pulleys by hand.( note the crank wont spin freely) you will usually be able to tell witch ones slipping.

SURE IT NOT WATERPUMP OR POWER STEERING PUMP

You need a harmonic balance. Very common problem!

try changing the belt it might be squeeking it self or you did not replace the right part that was squeeking or another part was squeeking alnog with the idler

Take the belt off check the clutch fan and spin all the pullies insure they spin freely and do not wobble if any do replace them if all checks out ok put a new belt on. make sure the belt tension is not to tight should have about 3/4 inch play.

Take a bar of soap at touch it on the side of belt when it is running. Becareful!!! or spray some WD40 on it. Should stop it. If not it must be something wrong with whatever it is running. If that is a serpentine belt spray it. Soap is good on v-belts.
