What would cause a squealing sound if it is not the brakes or belts when engine is running on idle condition?

Check for a vacuum leak around the throtle body and intake manifold.

The belts are squealing because they are either loose or worn out.The belts are squealing because they are either loose or worn out.

That depends on how, when and where it is squealing. For example, if the brakes squeal when applied, the brake pads are probably worn down. A squeal from the engine compartment whenever the engine is running could be a loose serpentine belt (especially if the squeal changes a little when you rev the engine).

no a diesel does not produce vaacuum when running. but vehicles that require vacuum for the brakes have a vaccuum pump attached to the engine to supply the needed vaccuum

Check the belts. The most common cause of squealing is a worn or loose belt on the front of the engine.

Though there are several possibilities, by far the most common reason for that is a loose or glazed belt in the engine compartment.

If its a high pitch squealing while accelerating, then the previous owner may have turbocharged, or supercharged the engine.

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.

Allow the engine to idle for one minute, and press the brakes. Keep the engine running and absorb the temperature of the fluid.

Pedal pumps up fine, but when you run the engine, the brake booster applies more force to the lines. Thus compressing any air that may be in there. You will need to bleed the brakes more. I sometimes bleed the brakes with the engine running to correct this.

The issue here sounds like it's the master cylinder failing. It is not retaining pressure when the engine is running. The reason they feel fine when the engine is not running is because the failing master cylinder is not getting power, and in essence is being bypassed.

only if the engine is running and the alternator is in perfect working condition!

There is a good chance it's your drive belts. If it's worse when it's cold or when you start the car check your belts'

If engine vacuum is low the brakes will be difficult to push. Sometimes, if the engine isn't running well when it's cold, the vacuum level will be low and the brakes won't work well. Have someone check that out for you.

if its a manual sounds like the clutch no it is an automatic

If it's constant while the engine is running, it might just be an idler pulley or the AC compressor. http://www.autozone.com/servlet/UiBroker?UseCase=S001&UserAction=viewSimpleDiagInfo&Parameters=info

If you want to turn off the running lights off try to engage the emergency brakes. I have a 2000 Montana and that works.

sounds like you need to replace the serpentine belt

User Avatar

what is the running mate in engine

User Avatar

Belt loose or worn out. Also possible a bad water pump, or bearing failure in the alternator or serpentine belt idler.

User Avatar

Water from the road has splashed up into the engine serpentine belt causing belt slippage that makes a squealing noise. The sqealing is one of your engine assessories that use the serpentine belt to drive it.
