The bearings in the fan clutch, or idler pulley may be going out, which would create extra resistance. This would cause the belt to squeal until everything is moving like it should. Try to lube the bearings, and put some belt stop squeal spray on the belt ridges. If this doesn't help, take the belt off and find which pulley is causing the extra resistance.

Ian,
There are two fans in a vehicle, One is in the engine compartment and is for the radiator. The other is in the passenger compartment and it runs the heater and air conditioner air flow from the plenum. The condenser is near the radiator and the evaporator is in the plenum. Condensers don't fail. Neither do evaporators. If the squeal is coming from the engine compartment when the air conditioner is turned on, the problem is either the belt to the COMPRESSOR or the CLUTCH on the compressor.

Engine screeches when running. revving the motor makes it stop momentarily


Could be a belt screeching. Fan belt, A/C belt, Serpentine Belt, alternator belt, etc. Easiest way to isolate which belt is to open the hood and use your ears to see where the screeching is coming from. Left, right, front, behind the engine? Spray some WD-40 on the belt you think is making noise and if it quiets right away, then that is the belt making the noise. Either the tensioner needs adjusting or the belt needs replacing. The WD-40 does not hurt the car, it'll start screeching again in a few days when it wears off.

AC Clutch noise and vibration


An A/C clutch will not make this concern happen, more likely the A/C compressor is begining to go out. The belt on the A/C clutch Assy. free wheels (spins feree on the pulley) when clutch is not engaged. If concern is not present with A/C off this means the bearings in the puley assy. ok. Once the A/C clutch is engaged it locks the compressor against the spinning pulley and turn the compressor chaft and spins the A/C compressor internal shaft. If you hear a loud "screach" when you turn on the A/C it means the belt slipped for a second, if it continiues to screach it means either the belt is loose or that the compressor is internaly locking up. I wouild start by checking the belt tension (if not equipted with and auto tensioner). You can also remove the belt and turn on the A/C and attempt to turn the clutch/pulley by hand, it should turn with a little effect but should not bind or lock at times if that happens compressor is bad.

Hyundai Sante Fe makes a screeching noise when I run the fan for heat or air conditioning. Really bad in the rain and is very lould. What is it? I've had the belts checked


Wow, I thought I was the only one to have this issue. I've even taken it to a shop and they claim they have no idea what is causing this. I always have to turn the fan off to make the noise go away. After a few minutes I can put the heat or air conditioning back on and the noise is no longer there. There are days when I have to do this every few minutes, especially in the rain.

How to stop the airconditioning belt from screaming


If it's loose it can slip when the a/c comes on and screech.
If it's not loose but screeches when the a/c is on then the a/c clutch or compressor is locking up.
If it screeches any time the car is running it can be any of the pulleys. Take the belt off and see if any are hard to spin. Be sure to check the idler pulley also.

I have changed the fan clutch and waterpump now there is a constant screeching noise when u slowly pour water on the belt it will stop for about 20 secs.What could it be?


Need to change the belt as it could be worn or tighten it more. There is a gauge to checks belt tension. Would be useful as overtighting could cause bearings to were over time

Hello, I purchased a 2003 Hyundai XG350 last month. When I start the car, put AC or defrost on, and then start driving there is a screeching noise that lasts for 10 seconds and then goes away. If I stop...


See if it goes away when you turn the A/C off. The a/c comes on when you sre in the defrost so yo don't hit the windshield with hot air. The screaching is more than likely the A/C clutch trying to engage, that why it was overlooked or ignored by the mechanic. It is a common thing. The battery should be allowed to recoup from the starting of the car which a few minutes of running woll help so the a/c clutch gets full battery voltage to function.. Turning on the defrost and /or the A/c after about 3 minutes of warm up. Open your hood and have someone turn the a/c on and off, you can hear and sctually see the a/c clutch doing its irritating thing.But keep your fingers out off the engine and don't lean over it with loose clothing. Good Luck, Ned

Screeching noise, then a/c stops blowing cold air. Still blows air, just not cold air.


it could be the air conditioning clutch going out. to check turn your car on and idle it with ac on and hood open. at the ac compressor it will have a pulley on it with a clutch that engages when the air conditioning is on. if it engages and disengages it can be the clutch itself has gone bad, the ac clutch will also disengage if there is not enough freon in the ac system, will also engage and disengage if the pressure gets too high in the ac system. Depending on the year of the vehicle it will disengage at full throttle and come back on when you are not at full throttle.
If it is a metallic sounding screech for example take a coke can and drag it across pavement kind of sound it could be a bad compressor or a bad ac clutch. If it is a more rubbery sound for example a car spinning its tires kind of noise it could be a loose belt.

1. Check to make sure all belts are tight under hood
2. start car and look at ac compressor to make sure compressor pulley is turning and that the fan clutch is engaged spinning
