Assuming you have already checked the obvious, the serpentine belt tensioner and belt. A common cause of the squeal in 4.0 Ford engines is the camshaft sychronizer (takes the place of the distributor on DIS, distributorless ignition systems). It sounds very similar to a belt squeal and is often mis-diagnosed as a belt being loose or worn. The noise can be intermittant, but if the noise is there when you have the hood up use a simple mechanic's stethoscope to help pinpoint the source of the noise. == == The most likely culprit is a serpentine belt or the belt tensioner. Try replacing the serpentine belt. If the noise persists, replace the belt tensioner. See the related article "Serpentine belt and Tensioner FAQ for the Ford Explorer all models"

What would cause a squealing noise from front end of 1995 Camaro that is quieter when brakes are applied?

Start with the most likely andeasiest to fix. Check your brake pads... There is a wear indicator on the inside pads (closest to engine) that will rub on the rotor and make a squealing noise to warn you that the pads are getting thin. When you apply the brakes the noise will go away a lot of the time. If the pads are new or not making the noise then I do not know what the problem may be.

If it's a manual transmission, it might be the throwout bearing. However, this noise would only occur with the clutch pushed in. If it does it after you let the clutch out then it might just be an accessory belt that needs tightening.


What causes a squeal noise from hyandi sonata?

Squealing from the engine (ie; it alters according to revs applied) would suggest a belt is slipping somewhere. Squealing that varies according to road speed suggests that the is metal contacting on metal. If it is when you brake, I know that some Korean cars have brake pads that squeal when they are worn to the point of replacement. I had that happen to me on a Kia once, and it scared me witless to start with!


What would cause an inconsistent squealing noise that stops when you apply the breaks on a 1997 Saturn?

This may be caused by the warning tabs on your front disk brakes. The tabs are there to alert you that the pads have worn down to the point where they need replacing. Don't go too long without replacing the pads once these tabs start squealing. The result would be that the rivets that hold the pad material in place will grind into the metal disk, possibly ruining it beyond repair.

Noise around the belt on 1989 Celebrity?

You need to be a little more specific about the noise around the belt. I would suggest you check out the serpentine belt as it could be failing. If it is a grinding or squealing noise it could be a failing bearing in one of the units the belt powers. I hope this is of some help, if not ask again with more information.
