2000 toyota celica is making a grinding noise by the belt like theree is a bearing going bad but if I spray some belt dressing on it it will go away for couple hours..

If it is a V belt, take a dry bar of soap, and apply it briefly to both sides of the belt. If the belt is making noise it will instantly ******* (but only briefly). For a serpentine belt you can lightly spray the belt with belt dressing. If it's the belt, you'll get silence, but there will be no effect on a pulley bearing going bad.

Sounds like a loose belt.

There are a few things that can cause a belt to slip like that.

The belt could be not tightened all the way. If it uses a sepentine belt with a tensioner, the tensioner could be bad. If it is not a serpentine belt, then you will have multiple belts and the one that is making the noise can be loose. Use something to pry it tight and tighten down the bolts holding the component th belt goes to.

It can also be a bad pulley. Pulleys have bearings inside of them, at times the bearings will go out and make the pulley hard to turn. You can usually find this easily by taking the belt off and turning the pulley with your hand. If it is hard to turn or makes a grinding noise when turned...it is bad and needs to be replaced.

Old belts can also cause this along with a belt that is wet. There is a spray on Belt Dressing that helps get rid of noisy belts, but I consider that a bandaid to a bigger problem.

With the Engine Running and belt rotating: Spray Belt Dressing (available at most auto parts / general merchandise stores) onto the Belt. Does the "whinning" noise go away? If so replace the Belt.
Turn off the Engine.
If the Belt Dressing does not stop the whinning: Check the Power Fluid Level. Add Power Steering Fluid - if necessary.
With the Engine Off: Remove the Serpentine Belt.
Click on the following free Link for the Belt Diagram and Directions on how to remove the Belt. Go to the left (counterclockwise) to relieve pressure off the Belt and remove the Belt.

After removing the Belt:
Go to the side and look at the alignment of all the Pulleys. All Pulleys should be aligned with each other. No Pulley should be canted/leaning.
Using your hand: turn the Power Steering Pump Pulley. The turning should be smooth and without effort. If there is any resistance or squeeking at anytime while turning, then the bearings in the Pump are going-out, and the Pump should be replaced.
While the Belt is off: check the remainder of the "free" Pulleys. Do Not turn the Crankshaft Pulley (you shouldn't be able to - by hand).

Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.com!

Any Auto Parts store or even a Wallmart may have a WD 40. I would first try to spray this behind or right where you see the Axel of this Idle pulley.
Unfortunately it may be getting old and dried out.
If you have any grease or even - sounds funny - Vaseline - try smearing this on where the Axel meet's the round pulley.

Most likely no, check to make sure that all of your pulleys are turning correctly with the belt. If the pulleys are all turning then the thing that is probably causing the noise is your belt. Go buy some "belt dressing" from an auto parts store and spray all over your serpentine belt. Sometimes your belt gets water on it and will squeal afterwards, the belt dressing helps correct this. Hope this works, let me know what happens and I will see if I can help more.

This could be 1or 2 things. It could be the belt, or a pulley making the noise. There is a product called 'belt dressing' that can be sprayed on the belt (it's an aerosol spray can) which may solve your problem. The problem is usually the belt becomes 'glazed' and a slight slippage can make the noise you describe. The belt dressing provides a better grip If you have to reapply the dressing often, it may be time to change the belt to stop to squeak. The other possibility is a bearing on the pulley shaft is making the noise, most likely in the ac compressor. It can be annoying, but won't harm anything at this point.

change serpintine belt I had one that it made noise changed belt noise went away

It is either your serpentine or another belt such as an alternator belt causing the squeak.

This can be resolved by either replacing the belt or making sure the tension is correct.

If it is a serpentine then replacing it will be necescary if it is alternator belt there are ways to tighten it.

Belt dressing is another temp fix for the squeal. the belts become glazed over time and will squeak and chatter spray some belt dressing on it and the squeak will go away for a while.



How loud is the squeak? 1-10

you need to change the water pump

you need to change the wheel bearing. you need to pull out the whole hub and the bearing has to be pressed out and in again with a new one
