Depending on the model it could be a belt alignment problem, loose belt or bad bearing in a pulley. If the squeal gets louder if you spray water in the area of the pulley it is most likely a loose belt. I would start by looking at the belt itself first then spray WD-40 in the bearing area of the Idler pulley and tensioning pulley. If the WD-40 works the problem is a bad bearing. Otherwise it is again, most likely, a loose belt. As a final check you can spray belt dressing on the belt and if the squeal goes away then it is your belt being loose. This could be caused by a belt being stretched over time or a tensioner not working correctly due to a weak spring, if equipped with spring loaded tensioner. If it doesn't have a spring loaded tensioner then you may just need to tighten the belt by adjusting it.

SOURCE: High squeal from engine area

i would suspect one of the idler pulleys, alternator bearings, water pump baring, you can isolate the location of the sound by using a short piece of hose, hold one end at your ear and with the engine running and the squealing noise evident carefully aim the other end of the hose at the deferment pulley locations, as you get closer to the noise source you will hear a marketable rise in noise you hear through the hose, careful not to get the hose caught up in the belt

Common Car Noises and Their Likely Causes Noise More Details Likely Cause Fixing It Clicking noise while turning Starts faint, gradually becomes more noticeable until very loud Failed outer CV joint (constant velocity joint) due to torn boot (most likely) or old age Replace either the whole axle assembly (recommended) or the outer CV joint Water pump noises Difficult to diagnose because of water pump's location Noise usually caused by damage to the bearings in failed water pump Only cure is replacing it. If possible do it at the same time as a timing belt replacement to cut down on labor costs Squeak or squeal from an engine belt Loud, high-pitched squeak or squeal Belts either need adjustment or replacing If belts only squeak when damp, they probably just need adjustment. If they squeak constantly, they probably need to be replaced Exhaust heat shield noises Rattle that you hear when car is idling Damaged heat shield Replace heat sh

If you think the noise is coming from the engine, you could take each belt off one at a time and run the engine to see if the noise stops.

What would cause whistling noise near pully and belt area noise gets louder with acceleration


The engine serpentine belt may be worn or wet. The belt slips, causing a high pitched squealing or whistle noise. The other possiblility is a bearing beginning to go out on one of your belt driven components

When it is cold Idont here noise from front of engine all ready changed Altanator it sounds be low the Altanator


I have the impression that you are asking about a noise from the engine compartment. Most of the time a squealing noise is caused by the idle pulley bearings going bad. When this happens the pulley stops spinning and the belt going across it squeals. You will need to replace this pulley, and and or the tension pulley. Either one can cause this issue.

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.

Engine Squeals


i would have to say that the timing belt is worn and stretched out for normal wear and tear. The check engine light is probably for the same reason. If the timing belt is not quite right it will throw a timing code for the camshaft being out of sync due to the excess slack that is in the timing belt.
