After your vehicle heats up, spray your belt with water. If it squeels, it's a belt. If not, it'll be a tensioner or pulley.

SOURCE: loud squealing noise

Probably a belt getting loose or worn. If alternator has a separate one than the rest, try just tightening it up. My guess is that it's probably all one belt with a tensioner pulley, which means you can't tighten, (spring tension already applied by tensioner) you have to change the belt, to get rid of noise, and if noise comes back in short time, think about changing tensioner.

I changed all 4 brakes on my dodge stratus and since there has been a loud squealing noise when I brake. I dont hear it when im in reverse. Its very loud when turning and braking


Most new cars come with ceramic disc brake pads to reduce noise. Aftermarket brake pads, depending upon materials in them, can be prone to squealing. Some pads come with adhesive shims that are designed to absorb vibration and reduce or stop squeal. There is also a compound you can but to put on the back of the pads to do the same thing when you install. Sometimes the noise will go away once the pads have had a chance to settle in .Some are just ornery and won't shut up.

Volt meter reading low squealing sound very loud


The squealing noise is a warning (you must have a murphy type gauge). Once the low voltage problem is solved the squealing will stop.

I have a loud squealing noise upon starting the car. the squealing normally lasts about 30-45 seconds. sometimes the noise will appear aftrer pulling off from a stopped position, as well. all belts


Try to tighten the belts a little firm.Sounds like when engine idling no squelling only when about to take off .Some times belts may seem ok on the outside but if you look on inner side you tend to see cracks in the belts .

2000 montero sport: There's a loud squealing noise coming from the engine. What could be wrong?


Squealing is most common with loose or worn belts, I would start by replacing the drive belt on the front of the motor and go from there, Its easier to troubleshoot a squealing motor if you know that the belt or belts are good.

Loud squealing sound in my engine


Try removing the belt and turning each pulley by hand. If everything is smooth and free, with the belt still off, drive down the block once and see if the noise is there (this will eliminate all rotating accessories on the front). If you hear the noise, then there is a problem deeper inside. Oil pressure is good? Dont' forget when doing this, you will have no power steering, so be careful.

Loud squealing noise


The noise is most likely the serpentine belt. Check it's condition and that of the belt tensioner. It sounds like the belt is slipping, causing the squealing noise u describe. As the belt warms up, it's getting a better 'grip' and the noise stops. Turning on the heat also turns on the a/c in newer cars, this added drag on the belt (one more component to turn, the a/c compressor) would explain why it happens when u turn on the heat. Is the belt original? If yes, it's time to change it, and check the belt tensioner to make sure it's doing it's job of keeping the belt snug on all the pulleys. Let me know how u make out.
