Squealing Accessory/serpentine Belt

[TaurusSE98]

Yeah, squealed again today. Sprayed some white lithium grease in there and wd40 all over the belt and pulleys. Of course it's nice and quiet now...

I'm not saying soak it overnight, just a little shvitz and the noise goes away. Believe me I can tell the difference in sound between a pulley bearing going away and a simple belt squeak.

I have done this for years and have never experienced a belt failure.

Every time there is a post about belt noise and I mention this solution, somebody jumps all over my stuff and tries to say how bad it is. Wel,, from now on, enjoy your noisy belts......

I am willing to give the WD-40 a try. It works great on keys, in spite what you have made heard, use once a year and your keys and locks will thank you.

Exactly what part of the belt do you spray with WD-40? Thanks.

a water pump on it's way south can, and probably will, squeal.

I tried it but it seemed to make the noise ladder. Oh well, it was worth a try.

Just replaced it and it still squeals.

Did anyone ever find a reliable fix to the belt squealing on the Vulcans?

Mine is chirping like a cricket, spraid WD-40, lithium grease on the idler and even the whole belt - it made it worse!!

Then I tried the soap trick (a bar of soap pushed under the belt grooves as it was turning - a little dangerous, be careful. Completely went away!!??

Then this morning it was back when cold. So then I took a long screwdriver and just ran it along the crank pulley grooves as it was idling to try and get the crud out of the grooves the serpentine rides on (very dangerous - be very careful). This seems to have the best results - I pretty much eliminated all the chirping except above 2000 rpm it will chirp slightly.

My latest theory is rust or crud gets on the pulley grooves rubs on the belt causing the annoying squel..It seems to be coming from the crank pulley? On mind I found moving the belt away from the engine eliminated the squeal and pushing the belt into the engine while running made it worse. I used a wooden pry bar to do this at idle so I would not do any damage,

Amazing, never seen a problem like this. The belt is good replaced 4000 miles ago with a genuine ford serpentine belt!??

I own two 2007 Taurus; one squeaks and one does not. The squeaking comes and goes; it seems worse when the outside temp is warm and is much less or gone when it is cold. It has been going for more than two years now in spite of new water pump, new pulleys and new belts (2 or 3). Tried WD40 on it seemed to make it worse. It sure is a pain in the butt. If anyone ever finds a sure cure, please post it because many of us want it to go away.

Squealing like a pig again today right at 2000 rpm - it's embarassing going down the road it got WORSE with me putting silicone grease on it!?

I thought it was the waterpump pulley bearings but that seems okay - no change even if I grease the water punp spindle.

I found from the owner before a workorder from a Ford dealer to repair it last August less than 4k miles ago. There fix was to replace the belt.

My last ditch effort was to spray turtle wax tire shine on the crank pulley while she idles - squeal sound completely gone at all rpms. Was worried about belt slippage but no issue so far. Will see how long it lasts, may just keep the bottle with me in the car.

You have an alignment problem. The chirping will keep coming back until you fix the root cause and align all the drive pulleys. Watch these two videos:

Tried everything on mine. Replaced pulleys, a water pump, multiple belts, nothing helped.

Changed to a Gator Back - problem solved. Good for over 3 years now.
