Belt whines and sounds like a bearing going,WD40 takes noise away

Belt Grip helps but noise eventually comes back,engine is 60,000 km old. The noise sounds like a bearing going but a small squirt of lubricant takes away the sound immediatly.

    A single belt with auto tensioner.

    I had the same problem and tighting the belts worked for me, you can do it by simply cranking down on the bolts that add tension on the pulleys

I'd remove the belt/belts and check all the idler pulleys. Did you retighten the belts or is it a single serpentine belt with an auto tensioner?

    I would replace the belt, the tensioner and any pulley that has noise when spun by hand.

Duratec ford whining sound


Most whining sounds come from the belt area and are caused by a bad bearing in a pulley. You can remove the belt and start the car to see if the noise goes away. If it does, you need to spin all the pulleys by hand to check for roughness/looseness.

Whining sound and lost acceleration. Sounds like noise coming from pully? Whining increases when pressing the gas.


The lost acceleration is of major concern. Maybe you have lost your water pump. It would work great for a few miles when you start out and then gradually heat up and loose performance. The fluid would eventually boil over? Maybe a bearing on the camshaft is expressing it's discontent and causing extra load for the engine to overcome. Try to determine where the noise is coming from.
The serpentine belt connects the alternator, water pump, power steering, front timing pulley, fan, and front timing pulley. All these components generate a parasitic load on your engine. If the engine has to work harder because of increased load it could be any of these components. I'd definitely check the water pump listening for noise while running. Look for obvious things related to the belt and its' components.
Check the serpentine belt for wear. May indicate pulley misalignment or wear. There exists two idler pulleys that have small bearings that wear out and squealing noises. Check those for wobble with the tension off the belt. They are pretty cheap so replace them if any concern at all.
Power steering pumps cavitate and make a high pitch gear whining sound if fluids are low or gears warn of. Check the fluid and top off to the correct level.
Best wishes,

Be carefule of hot parts and rotating/moving belts and pulleys.

If its a whine, most likely the bearings on the idler pulley or the bearings on the ac compressor clutch.
-To trouble shoot with engine running and ac on spray wd40 on bearing area of clutch then wait a few seconds to see if sound goes away. If not then try bearing area(behind bolt of pulley) of idler. This will work as temporay fix, but ultimatly you must replace bad bearing.Do NOT spray on belt or pulley surface.

If its a squeal could be the belt is loose and needs to be replaced or dressed.
-Belt dressing can be spray directly on belt while engine is running and ac is on.

Same problem: a high pitch whine after extended driving


Sounds like a dry/failing bearing or power steering pump noise. You first need to try to track down where the noise is originating, and the most likely place is at the front of the engine.
I would start by listening with the hood up while parked with the engine running and the noise present, and seeing if it is coming from there. If so, the most likely cause is something connected to the belt - e.g. AC compressor clutch, tensioner, power steering pump, or generator. Can also be caused by the belt just slipping (warn out belt, tensioner not working properly).

Noise from area of serpentine belt.


The best way I have found to locate a belt noise is to take a can of WD40 and spray it on the belt when the engine is running. (be careful of the fan) If the noise goes away, you know that it is a belt noise and not a bearing. When serpentine belts dry out they make funny noises. Hope this helps, cheers

Engine whinning


I had the same problem on my 2005 Envoy. Turned out to be the idler pulley bearing. It is just a pulley the belt rides on. The bearing in the pulley was what was making the high pitched whine. I replaced the bearing, and the noise went away.

Camry 2.2 engine whine


Some alternators will complain during higher output to replace the charge you used in starting the car.
An old mechanics trick is to use a screw driver, held with the handle pressed firmly behind your ear (bone conduction) and then press the tip on various (NON-rotating!!) accessories to isolate the source of the noise.
An old mechanic friend could tell you exactly which bearing, crank or rod, was rattling and predict how long you had before failure.
