Does it sound like a dying water pump?
the squiqing comes from driver side

I was unable to see anything. The audio sounds like either a pump bearing or a belt tensioner pulley bearing (and you want it to be a tensioner pulley bearing).

Use a 1/4" drive ratchet or bar to release the spring tension and check the tensioner pulley bearing for roughness by rotating the pulley through the complete 360 degrees of travel.

If the tensioner pulley rotates the least little bit less than glass smooth, replace the tensioner assembly (I know of no source for the bearing only).

Otherwise, your next likely suspect is the water pump cartridge.

thank you for your quick reply. i'll check it and post again.

i think i'm lucky. The tensioner pulley bearing rotates pretty rough.
To replace the tensioner, do i only have to take out the two screws that sustains the belt cover too?

Plus whatever else might interfere with the task.

When my tensioner bearing went out I just peeled up the orange seal around the bearing and packed it with some high temp grease.... It works great now and I was able to save the 80 bucks napa wanted for the tensioner setup.

Just my .02

For who's got the same problem, check this out:

i don't think i have to change the whole assembly.

I found a store that carries only the bearing. Can I easily replace the bearing or is more difficult and I need a press or some other tool to take the bearing out? Is the bearing only thing that breaks?
The bearing is $9, the pulley $ 33 and the whole assembly $ 56. What’s the best deal in relation to the time I have to spend to replace each of these parts?

Spend the money for the entire assembly.....the spring and pivot wear also. Cheap long-term insurance.

NortHStaR is living on extremely borrowed time. That "stuffed" bearing is going to fail at 1230 AM on a twisty, dark back road. Guaranteed.

Yea, do your self a favor and replace the whole thing...

The other day my idler pully failed. Your bearings could be ate up. Seriously.

Wanna see what i found when i removed my idler pulley yesterday?

Yea, this is exactly how it looked when i took it off.

Before it failed, I was hearing friction noises. Squeek, screeeech, and somtimes it would get quieter. Then i was on my way to a gas station. I heard a fast knock/vibration noise. and really loud screeeching noise/rubbing noise...POPED the hood. Seen metal shavings everywhere. and the pulley was wobbling.

Now. If that belt would have came off. I would have been in pure hell.

Replace it.

Oh, and you can see that not only ball bearings are missing. But both of the protective bearing seals were ate up and desintigrated.

Actually my Silverado has had repacked grease in the tensioner bearing for about 35,000 miles now, not one problem, my N* has had the water pump tens. pulley done for around 15,000 again no problem.

Its not borrowed time my friend its finding ways to work around spending GOBS of money that isnt necessary.

Call it what you may, it works for me and I'm just trying to share what little I do know with people that may benefit.

Be careful - we have heard of tensioner pulleys that locked up and that caused the drive pulley on the camshaft to get ruined because it was trying to turn the belt that was locked up. Personally, I would replace the whole thing, but I guess just the pulley and bearing would work if you are in a cash bind

Thanks all. I replaced only the pulley and bearing before i got your replies, because i couldn't stand the noise anymore. Now i think the other tensioner started to make some noise. Maybe it was caused by the low temp in the last month. If I hear any noise again I’ll change the whole assembly. Is it too difficult to get the belt back on its place or I can just use some clamps to avoid taking it out of all pulleys?
