2001 Ford Taurus, front end noise. This sounds like squealing. I recently changed the idler pulley, but still noisy. I changed the water pump and belt only about 5 months ago. Does the alternator have bearings that might squeal? Can't seem to figure this one out. Your help on this will be much appreciated.Thank you

    Yes you might be right about the belt. The squeal stays constant at idle, then gets faster when you start going.Could it be something as simple as replacing the belt?My a/c compressor doesn't work, so this belt bypassed that component. It seems that it wore out fairly quickly, if that's the problem? Thanks again

    Yes, I believe you're right about the belt, because it gets louder and faster with increasing the speed but stays steady at idle. The a/c compressor went out some time ago and I bought a different size belt from Autozone to bypass that component. Could the belt already have gone bad? Thanks for your help

    Are you sure it isn't the belt squealing from not being tight enough or is it a different type of squeal? Does the squeal come and go? Does the squeal only happen during certain times? Does it get louder with the faster you go?

I might not have enough information but the squeal is most likely a worn bearing. Try to isolate it with a "mechanic's stethescope" to locate the source. A pin point shot of WD-40 at the whining bearing (NO NOT put it on good bearings should TEMPORARILY quiet it IF it is a bearing. DO NOT overspray, just at the center of the pulleys...the lubricant should get pulled into bearing to confirm that the pump (power steering would be my guess) needs replacing.

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.

SOURCE: Chirping, squealing noise from pulleys

check your pulleys. but if you have a Dayco belt on your truck, sometimes they're noisy. Its just the design. But they're good belts. But I would check the pulley on your water pump first, just in case of bearing wear. That's the best way to start.

Why is my car making whining noise by belts and pully

One of the accessory bearings could be going out
(I.E.-alternator,water pump,etc)If the noise is near an idler or tensioner pulley,it could also have a bad bearing.The best thing to do is remove the serpentine belt or release the tensioner pulley so the belt is loose,then you can spin each accessory pulley by hand and listen for the noise.You'll also feel the pulley dragging while you spin it and it might have a ratchety feel to it(in other words,as you're rotating the pulley you'll feel it spin somewhat freely and then it will feel as if its catching on something) If the belt itself is bad,it usually makes a squealing or chirping sound.If your vehicle has a vbelt drive with multiple belts,check the pullies the same way as described above and make sure the belts are all tight.A loose belt normally causes a squealing noise rather than a whining noise.Check your power steering fluid level too because the pump will whine if it gets low on fluid.

Serpentine belt on 2006 Ford Taurus SEL squealing.

The belt has most likely moved either in or out on the bottom pulley. Check it first. I had the same problem it looked ok but was out one groove missleading designed pulley.

Loud squeal

Hi there
Your problem could be either Alternator bearing or water pump bearing ,both of these are normal problems, so sorry to tell you but you have to remove the belt again and spin the alternator pulley and see if it has a groan noise and the same with the water pump.
Your problem should be 1 of them OR the other problem is bigger and thats the bottom engine front pulley SEAL but thats only 1 in 1000 times so hope its one of the other two.

Sounds like the power steering pump. Usually water pump will leak from its weep hole if its going out. Look for coolant leakage around bottom of water pump.

2001 escape squealing noise when engine is under presure

Use a mechanic's stethoscope to locate the culprit sqeal. Have a technician rev the engine, in order to produce the squeal. Lay the stethoscope tip utop the water pump, nearest the armature. Locate squeal in this fashion against the idler pulley(if applicable), the alternator, the air conditioner compressor, power steering pump (if applicable), the cam shafts (if applicable), and finally the crank. This will help isolate the location of the squeal.7_20_2012_9_07_34_pm.jpg

I have Ford Taurus 2001. There is a screech sound near the belt.

That would be your belt tensioner and or water pump or idler pulley. Only way to found out take the belt off and wiggle each one.
