SOURCE: change serpentine belt and tension pulley and idle pulley and

could be the alternator, water pump
take the belt and spin all the pulleys and listen for noise and make sure they turn smoothly
another trick is to take a can of wd40 or equivalent and spray the bearings 1 at a time till the noise goes away or quiets down

SOURCE: loud chirping noise when acceleration pedal is

There is a TSB (Technical Service Bulletin) for this problem:

Engine - Accessory Drive Belt Noise Diagnostics/Tool
08-06-01-008 03/27/2008
This particular vehicle had an issue with pulley alignment, particularly the power steering pulley. Take a look at the shaft the pulley is pressed onto. If the end of the shaft isnt flush with the pulley, it is out of line and will cause a squeal.

It is recommended that you discuss this TSB with your dealer (not local mechanic).

I hope this helps.

Below is a diagram for the belt routing on your Yukon. The belt tensioner is the top left pulley as you look at it from the front of the truck.

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.

2004 ford taurus chirping noise when engine revs


Hello, There are several things which can do this. First, cut off the A/C and then rev the engine as before. If the chirping goes away, the noise was either the A/C clutch or the Serpetine belt slipping with the load. For the A/C clutch, you can try a little rust removal between the drive plate and the pulley with the engine OFF. You can use sandpaper and try to knock off the rust. Then put a little oil on to condition the metal. Then try it with the A/C on.

If the chirp is still there, you have to check bearings on the Pulley tensioner, Alternator, Water pump, and Power steering. It is possible for the Pulley tensioner to have a weak spring or you may have a stretched Serpetine belt. This condition would cause the belt to skip under a load. If the belt is checked with small cracks, just replace the belt. Take off the tensioner and compare the spring tension and wobble in the pulley to a new unit at the Autoparts store.

If still no success, the chirp could be a water pump bearing. The old way off using a piece of wood on the housing of a part while the engine is running is dangerous, but effective. I believe you should have already found your problem before this measure is needed. Dry Serpetine belts make quite a lot of noise and is probably your problem.

I hope my Solution is very helpful to you.

93 Diamante making clanking sounds under the hood. From fairly quiet to fairly loud. Sounds like it's coming from the belt area, a/c ciompressor area of the car.


This could be caused by different things. It sounds like it may be your timing belt though. If you remove your drive belts (alternator, power steering and air conditioner belts), and then restart the vehicle, if the noise stops, then spin the pulleys you just removed the belts from, to see which one is making the noise. If the noise does not stop, then it is most likely the timing belt tensioner making all that noise and you will need to have the timing belt and associated parts, idler pulley/s, tensioner, water pump and seals replaced. Hope this helps. Have a nice day :O)

The 2001 Windstar we have here only has 7 pulleys and the diagram dosnt match any ides.


here you go. please rate, thanks

s1w~us~en~file=ani_caut.gif~gen~ref.gif CAUTION: The drive belt tensioner has no provision for adjustment and will be damaged if forced to travel beyond its operating range. Automatic tensioners are calibrated at the factory to provide the correct amount of tension to the belt. There is no need to check tensioners for proper tension.
NOTE: Drive belts (8620) with automatic drive belt tensioner (6B209) do not require adjustment.
NOTE: When a drive belt is installed new or reinstalled after a service procedure, the drive belt does not fully seat into pulley grooves until engine has run for several minutes.
This vehicle is equipped with:
  • a V-ribbed serpentine accessory drive belt.
  • automatic drive belt tensioners.
New drive belts should be of the same type as originally installed.
Drive belt chirp is a regularly occurring chirping noise that occurs due to:
  • pulley misalignment.
  • excessive pulley runout.
It can be a result of a damaged pulley or an incorrectly replaced pulley that was not correctly aligned.
To correct drive belt chirp:
  • determine the area where the noise comes from.
  • check each of the pulleys in that area with a straightedge to the crankshaft pulley (6312) for front accessory drive and the water pump drive pulley to the water pump.
  • look for the accessory pulley to be out of position in the fore/aft direction or at an angle to the straightedge.
Drive belt squeal is an intermittent noise that occurs when the drive belt slips on a pulley during certain conditions such as:
  • engine start-up.
  • rapid engine acceleration.
  • A/C clutch engagement.
Drive belt squeal can occur under the following conditions:
  • The A/C discharge pressure goes above specifications:
    • The A/C system is overcharged.
    • The A/C condenser airflow is blocked.
