Loose or worn belt. Possibly belt tensioner bad, but unlikely. Change or tighten belt if possible.

SOURCE: squealing noise under the hood

I had the same problem, it turned out to be the idler pulley, a 16-20 dollar part. I took about 10 minutes to change myself but an auto shop will do it for 100-120 dollars.

SOURCE: 99 Chevy Malibu belt chirping noise problem.

one or more of the pulley's is defective, most likely the tensioner pulley, but check them all for wear and side to side movement which indicates a worn bearing, this causes the belt to not run true and chirp.

You may have a lower intake manifold gasket leak (or a head gasket leak-slightly less probable) the lower intake can leak onto the serpentine belt and fling oil (and/or antifreeze). The lower intake manifold gasket is usually the culprit here. There is much information about changing it if you are inclined to do it yourself. If not, expect around 800 to 1200 to fix at dealer/mechanic. This is usually accompanied by (but not always) oil in the antifreeze, or antifreeze in the oil...

Probably should replace the belt. A worn belt will squeal sometimes.'
Another thought is the belt tight enough A belt that is too loose will squeal under stress .

Can't find the source of the squeal


Year make and model ??
The belt could be glazed and slipping even if it is tight.
You could have a weak belt tensioner too.
The noise when the ac or heat is turned on can be the extra load from the ac compressor or the alternator. The compressor cycles on and off especially in defrost mode.
The load from the alternator is the first noise of the day. As the belt warms up it becomes better at handling the load of the accessories.
Even tho the belt looks fine, you may have to replace it to get rid of the noise.

2005 xb squeals when I start the car then fades


I'm not sure where these other guys live but their solutions are nonsense. Coolant leaks? Fuel pumps? Dead or dying batteries? I too drive a 05 Scion xB and have had squeak issues. These squeaks and squeals are caused by one or both of the serpentine belts. If not the belts then the pulley's associated with the belts. One of the belts drives the power steering and the other operates the Alternator, Water Pump and AC Compressor.
Does your car squeak when you have the AC turned on and the fan running fairly fast?
Do you hear a rough kind of noise when you're turning the wheel? If it's either or those two then I'd check your belts.
But still to be on the safe side I'd bring it to a mechanic and have them check the belts for glazing or wear then go from there. If you can put belts on yourself they will run you about $40 for the pair. Most garages charge an arm and a leg for them and then another appendage to install them.

Best of luck

What makes the fan belts squeal?


New belts need to be readjusted as they stretch unless you have a spring loaded belt tensioner.

2003 kia spectra, 5 speed, had the belt replaced, now it squeals worse


I believe I know the noise that is troubling you. If a new belt is correctly tensioned and still makes such a noise it would indicate either contamination with oil or similar or pulleys that are less than perfectly aligned

The noise and your description is symptomatic of slippage and the pulley that is most likely to be slipping is the small alternator pulley. After starting and when accessories are being used that require a significant current the alternator needs considerable power to drive it in order to produce that current/replace the battery power used to start the engine.

The increased power to drive the alternator must be delivered via the drive belt. As the battery voltage rises the charge rate will fall and the power needed to drive the alternator falls and so the squealing reduces and then stops.

One further thing to note is an engine and it's ancillaries expand or grow quite a lot in engineering terms as it warms up, this has a tendency to tighten the drive belts further.

My 1998 Toyota Avalon XLS squeals loadly when I start the engine and the fan is on in the car. I turn of the fan and it stops. After driving I turn the fan back on and don't get the squeal anym


Almost certainly one or more of the drive belts (not the timing belt) on the engine needs an increase in tension. It may tell you about this in the owner's handbook.

If not you can either ask a mechanic to do this straightforward job for you, or try it yourself. You can download a zipped service manual from here

and look these belts up in the charging section and steering section.

Trying to figure out why i am having squealing issue all new altternator power steering pump pulleys and belts


Belts normally squeal when they slip and they slip because they're not tight enough or in the case of a V belt because they're too narrow. Make sure they're tight enough and they're the right belt.

How to change drive belt for 2006 chevy uplander


if you're refering to the serpentine drive belt, most are held tight with the tentioner & you will need a 3/8'' drive breaker bar to pull back on it & while doing so, remove the belt carefully & then gently releasing the tentioner. most have a square 3/8'' hole in the middle of it to insert the tool & is easier to remove from under the vehicle. hope this helps.

Belt squeals and it is hard to steer.


check to see if the belt is loose, if it is a sepentine belt, [one that is routed for your power steering , air conditioning, and pulleys it just might need replaced, also chech to see if the tensioner pulley has not lost some of it's tension. ]

2000 Mitsubishi Galant 4 cyl ES underhood squeal on right side


Be gentle with my rating. I am a long ways away. It sounds like a fan belt. You should pop the hood next time and see how it sounds when you have the squeeling going on. Fan belts will squeel until the get warmed up and then stop because the heat makes them grab the way they are ment too. Let me know, Raz
