SOURCE: Replace idler arm pulley

An idler arm is a steering component found on vehicles without rack and pinion steering. Your referring to an idler pulley. To replace: remove the belt, remove the bolt from the center of the pulley, replace the pulley and reinstall the belt.

You didn't mention the alternator, power steering pump, or water pump. In fact, any pulley other than the crankshaft one can have a bad bearing or dry seal. Remove the belt and spin each pulley while listening for any rough noise or squeal. If it was the crankshaft, it might be time to check the oil. Start the engine with the belt off to see if it does squeal. Make sure the noise isn't coming from the radiator fan(s).

The first thing I would do is remove the serpentine belt and then start the car. If the noise is still present than I would agree that the noise is in the engine whether it be the timing chain, valve train, etc. If the noise goes away than it is being caused by an accessory. Water pump, alternator, a/c compressor, p/s pump would be suspect. You can run it for a couple of minutes with out the belt at most. This will keep the engine from overheating since the water pump will not be turning with the belt removed.

Tensioner bolt bottoms out on idler pulley (belt for Poly-V A/C & Idler) on 2000 Nissan Pathfinder SE


Pulleys also wear.
You've changed the belts - a workshop would then change that particular pulley, if asked to do so.

Start your engine, then put a few drops of water onto that pulley. Does the squealing noise disappear? If so, the pulley is slightly worn in the groove - and this happens to all vehicles.

Your option is to either replace that pulley or use a spray-on anti squeal compound.

Ac clutch squeals when i hit the gas no matter if ac is on or off but not at idle 98 jeep gc 5.9 need steps to replace clutch assembly


Are you certain that it's the clutch assembly?
Check the idler pulley. Poor tension in the idler pulley spring will cause the belt to squeal AT THE ALTERNATOR, and it may sound like it's coming from the AC.
The AC pulley typically "freewheels" when the AC is not on and the engine is running.
Have someone turn the AC on and off while the engine is running and watch the operation of the AC clutch. If it's working properly, the clutch should "click" and the back part of the pulley should start turning or try to turn.
If the squealing noise continues when the clutch is freewheeling, it's probably the idler pulley. If the AC Pulley won't start freewheeling, it's probably the clutch.
To remove the clutch system,
  • disengage the idler pulley and remove the serpentine belt from one of the pulleys.
  • rent, purchase or borrow a puller from a local auto parts retailer (Auto Zone and O'Reilly auto parts are both helpful)
  • some of the clutch systems have retaining bolts, some are just pressed in, figure out what you have before removing the clutch assembly using the puller.
  • The puller is also designed to help put the NEW clutch assembly back on the shaft.
The idler pulley assembly is a lot easier to replace.

When I raise the hood and with motor running looking to my left there is a belt running and a squeaking noise at idle coming from that area. The van is front wheel drive so motor sits in there sideways.


Has it just started with cold weather? Does it squeal at first then as the engine is revved, stop squealing.

If so its probably your alternator belt has worked loose and needs tightening. I'd check this out first, if you've not done it before ask a friend with some know how for guidance. But as a guide, there should be about an inch of give when flexed on the longest run between 2 pulleys, if more then probably needs tightening. If more than a couple of years old, replace with a new one.

If it still squeals after tightening/replacing, you could have a faulty water pump bearing or pulley bearing. Either would require replacement to pre-empt catastrophic failure and resultant engine damage.

Have you tried to checking the tensioner and the idler pulley? The idler is a fixed pulley on the driver side of the alternator. Most of the time this gets rusted during sudden change in the weather or its just the bearing inside it just worned off.

1994 Camaro making a noise


Yes, it could also be the tensioner or idler pully making the noise. I would remove the belt and try to turn each pully by hand and at the same time try to move side to side to locate this.
