Probably an idler or tensioner has a worn out bushing/bearings in it.

    idlers and tensioners usually install with a single bolt through the middle of it...just grab the proper sized wrench. dont do up the belt too tight, you should be able to press it down with your finger about 1/2 an inch without pressing too hard.

My 2001 mazda tribute is making a whistle sound, when it's sitting still. Either at a red light, or in park, but wen I'm driving or excelerating it goes away

loose or worn out serpentine belt. just replace and noise should go away. even better buy a can of serpentine belt dressing and spray on belt............noise should be eliminated.

Chirpping in the engine

might be a bearing in your altenator or water pump, is it high pitched? does it go away if you rev the engine? if it goes away it might be the belt and u could try some belt dressing, its a spray u put on the belt that stops it from squeking

Squeking in front of the motor on the car

It could be your serpentine belt. Road tar can get into the groves of the belt and cause sticking to the pulleys which will translate into a squeaking or chirp sound. To check, with the engine running use a spray lubricant (not water and above all not belt dressing. The dressing will only make matters worse) If the sound go'es away that is your problem.

My belt making noise, if i spray little wd-40 on the belt, it goes away, but in few minites comes back.???????//

Yes, any belt dressing only lasts for a little while. You need to resolve the issue(s). First, consider replacing the belt, eventually they get shiny and make squeaks. Look carefully for pulley alignment, if off jsut slightly, the belt does not lay correctly and causes noise. Sometimes you can rough up the offending pulley and keep the noise away for a longer while, use coarse sandpaper.

Belts squek

Some old belts are worn, replace belt if this is the case. there is a belt dressing that can be sprayed on that may help as well. The belt must be properly adjusted, if to loose it may make the squeak as well.

Getting a 'squealing' noise from the engine all the time. What is the cause likely to be??

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.

My car squeals whil in idle but not so much when im driveing it

Get the serpentine belt inspected or replaced.

To test open hood and while its squealing spray some water on it. If it subsides for a few seconds then you know where the source is.

My idler pulley is making a squeaky light grinding niose.

Any Auto Parts store or even a Wallmart may have a WD 40. I would first try to spray this behind or right where you see the Axel of this Idle pulley.
Unfortunately it may be getting old and dried out.
If you have any grease or even - sounds funny - Vaseline - try smearing this on where the Axel meet's the round pulley.

Van brakes squeal/whistle even when stopped

Sounds to me like a dry, loose or worn serpentine belt. With the motor idling, lightly spray the serpentine belt as it's spinning with WD-40 or other oil based lubricant (Don't spray near the alternator). If this doesn't work, turn the mortor off and check the tension and for cracks or worn spots. The brakes will not squeal when you are completely still.
