Can't figure out where this noise is coming from. I used a hose to my ear and still couldn't locate it. Could use some help.

Play video from link. They all are the same video.

It can only be the belt, idler pulley, or tension pulley. Maybe something is leaking on the belt but probably not. All the pumps make grinding type noises when needing replaced.

The kit to replace all three, which only takes a socket wrench and about an hour, isn't expensive at any parts shop. The parts house belts and pulleys typically improve engineering too.

Spray some water on the belt while it's running if you want to see if it's just the belt.

 

First thing I would do is remove the fan belt and start the engine and hear if the sound has changed. Sound like a exhaust leak to me.

 

I have the 3.0 on my 2000. And the belt was driving me nuts. I changed pulley bearings and some pulleys, the noise was still there. So i put a washer in between idler pulley and bracket. That did it for me.
