    There is a noise coming from the engine compartment. I think it is a squealing belt.

It is your Belt Tensioner. You will need to Locate the Belt Tensioner. It has a Large Pulley on a Bracket that Has a Bolt in the Middle and a Smaller Pulley that Goes Under the Belt and Holds Tension on it. You will need to get a Wratchet, Socket, and Cheater Bar. Turn the Bolt On the Top Large Pulley with the Wratchet and Cheater Bar. This will Lower the Smaller Pulley So that you will be Able to Remove the Belt. and Replace the Tensioner Pulley Assembly. Please Rate My Response! Thanks!

You could have bad bearings on one of the pulleys...they sell some stuff called belt dressing in a spray can at the auto parts store that you might try

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.

Changed belt and pulley tensioner and I still have squealing sound when I step on the gas. nissan pathfinder 2005


There is quite an extensive service bulletin from Nissan regarding belt noise on this truck. It involves checking several things, two of which you have already replaced. The only remaining thing that appears to cause the problem is the one-way clutch that is mounted on the front of the alternator. Apparently they slip and cause this noise, and it sounds like this is your problem. They are a bit of a pain to change and probably expensive. Why they needed a one way clutch on the alternator, I'll never know, but that's the way it is.

I have a 2003 Nissan Murano, and everytime i turn the heater on now, there is an earsplitting squealing noise that happens for about 15 seconds. It started just when the car was cold, but now it will come...


alternator/air comp. belt slipping.look for loose belt,worn cracked belt and also these are known for cracking tensioner pulley mounting bracket and causing tension loss on belt.without a lift would be pain and ultimately you wouldnt really save much trying todo yourself.

I have a 1994 nissan pathfinder...there is a high pitched squeal coming from the engine, what might this be? sounds maybe like a bearing, but not sure what bearing, or even where these bearings are...


Hi,
That squeal could be just the belts, when starting at cold belts tendency is to slip and made some sounds. Check on that in early morning and start your engine and look at your engine to identify the sounds.
The bearing would be in the idler bearing that tightens belt of your aircon compressor.
Hope that helps you out!
Thanks for using Fixya!

Belts squealing


you may have a bad tensioner need to remove belt and see if tensioner moves freely or stays where you stop it at (they are difficult to mave anyway due to large spring on backside but you might be able to tell if not take it in and have checked)
I like to have people see why they need the parts i recommend so ask to see if you are not sure!

Loud squealing noise


The noise is most likely the serpentine belt. Check it's condition and that of the belt tensioner. It sounds like the belt is slipping, causing the squealing noise u describe. As the belt warms up, it's getting a better 'grip' and the noise stops. Turning on the heat also turns on the a/c in newer cars, this added drag on the belt (one more component to turn, the a/c compressor) would explain why it happens when u turn on the heat. Is the belt original? If yes, it's time to change it, and check the belt tensioner to make sure it's doing it's job of keeping the belt snug on all the pulleys. Let me know how u make out.
