screeching noise again...video inside

So I asked this question a few months back but didn't get much in replies. I have this screeching noise just above idle. I thought it was probably a bad tensioner pulley so i just replaced it with one from ECS. No dice, same noise. Its coming from that general area, i just dont really know how to narrow it down to which pulley or if its even a pulley. Does the water pump make a noise when its going bad, or the alternator? check out the video and tell me what you think. In the video im holding the throttle open just enough to make the sound, you cant see me as im off to the side. Just didn't want anyone to think that it was just idling spastically. Thanks

water pump can make noise yes, but not likely your problem. Check that all your belt pullys are spinning straight (Harmonic balancer, water pump pully, power steering pully, alternator pully). If all is okay simply check your timing belt cover on passenger side of engine. Play with it a little, move it around and see if noise goes away. They are designed shitty and my camshaft cog rubs on cover on cold starts for some reason. Same noise same RPM.

I dont notice any wobble or crooked when the pulleys are spinning. everything looks true. I will check the cover and see what happens.

Sounds like a pulley to me.

I never gave a damn about the meterman,...

-til I was the one who had to read the meter....

Gotta agree with Ninja here. It has the resonant sound that a plastic pulley makes when the spindle bearings go. You need to do some troubleshooting here. Pull off each belt one at a time and run the engine for a few seconds to determine which pulley is the culprit.

Of course, leave the timing belt intact. But you knew that anyways. If, after pulling the other belts, the sound is still there, then it is either the timing belt tensioner pulley, or the water pump. It it is either, then you might as well replace both, as well as the belt, since you will be in there anyways and will give you peace of mind for the next 60k miles.

Let us know what happens.

I can verify that the sound in the video above is caused by the Timing Belt Tensioner Pulley. I just fixed mine and that sound went away.

It's fairly easy to check. Just remove the big Airbox hose to get to the Timing Belt cover and pop that off. Then just loosen the Tensioner Pulley a little bit. Noise should lessen or be gone completely.

I put mine back together and have a new Tensioner on order. Not a big deal, and not expensive to fix. Less than an hour...

My noise - again, exactly like in the video - showed up a month or so after I replaced the Timing Belt and Water Pump, etc... I think I tightened the Tensioner too much and put too much stress on the bearing. Either that or it was defective to begin with. Hope this helps.

Yeah, and the car is from '98. And some of them will still make that noise! I came here looking for an answer to that same exact sound we hear in the video. So maybe I can't help the OP, but someone who's car develops this sound tomorrow might find this thread like I did...

And I hope they do, because I have to correct my last post. It's not the Timing Belt Tensioner in my case. I thought it was because the noise went away when I took some tension off it. So I posted here that that was the problem and ordered a new one. Well, the new one does it, too.

Given that the noise goes away when I lessen the tension on the Timing Belt Tensioner, it must be one of the pulleys on that belt. Crank pulley? Intermediate? I didn't disturb that when I did the Timing belt. Is it possibly just a cheap-ass, noisy belt?

Not the tensioner. Looks like the Intermediate Shaft Bearing(s) are shot. Can't easily replace it without pulling the engine. Apparently it is possible to loosen the engine mounts and tilt the engine enough so the shaft clears the wheel well, but I'm not finding enough info on that technique, nor having much luck finding the shaft/bearing replacement parts.
