It's "chirping" sound. Best way I can describe it is it being similar to one of these bird call things, but slightly lower tone.

It sounds as if it is coming from behind the glovebox. Not a constant squeal. Originally it only occurred while making left left hand turns. Now it is doing it while driving straight, as I hit slight road variations.) Seems very suspension biased, however, if i push the clutch in to drop the RPMs (while still rolling) the sounds subsides. With the car stationary, either at idle or reving I do not hear it. I just had the time belt, tensioner, water pump and a/c tensioner changed. This coincided with the change from the only-when-turning-left chirping, to the driving-straight-over-slightly-uneven-road chirping. Any ideas???

Does the sound go away when you shut off the climate control?

Could be squeaky stabilizer bar bushings, esp if they are poly. They all do that after a while as the lube dries out, gets worn/washed away, or contaminated by road dirt. Then, every time the suspension moves up and down just a little, you will hear that squeaking sound. Irritating.

Does it with climate control off also. So on a cold engine this morning I could faintly hear it right after start up. Blipping the throttle 500 rpm made it noticeable for a split second (as the rpms were climbing) AS DID turning the steering wheel slightly but quickly! So, pretty sure it's p/s related. Could it be just a belt, or can the pump make that type of noise??

Yes, it can did you check P/S fluid level?

Yes, I sort of agree check the fluid and belt tightness.

Have the girl turn the wheel while you are down below for a listen.

What ATF are you using BTW? If it is Mobil 1 ATF, might want to drain that and try something else. I have found a few cars make more noise with mobil 1 than say castrol or others.

So I have two "what's that noise!?" threads right now, maybe I'm too anal. Regarding this sound, while searching for the other, I was able to make this sound, with the car off! so not a belt, but probably a bushing somewhere? When I push down on the passenger's side of the front cam cover I hear the "chirp." It only needs to move slightly and it doesn't appear to be linked to the suspension, as if I push the fender to compress it, I do not here the sound. It is the movement between the engine and the body somewhere. Here's an attempt to capture with my cell phone. It sounds just this clear inside the car when going over bumps.

Oh oh oh, I know!!!?!? Check the nut on the front mount. Might be a little loose and scraping up and down on the bolt that is mounted to the mount. Or front mount is toast as man your engine move a lot. At least the in the video it looks that way.

Got it... it was stupid and obvious (but isn't it always?) Was not the front motor mount as Jason suspected, but I would not have figured it out without pulling the fender liner to check. Once I did that the sound now appeared to becoming from above. So pushing and listening I was for about 5 minutes until I noticed a hose clamp coming off the water pump rubbing on a piece of sheet metal just below the rear cam cover... At first I said, "You've GOT to be kidding me." Then I thanked the Alfa gods that wasn't something more serious. Turned the whole clamp 90 degrees and voila!

BTW, where does that go? The braided hose goes into a rigid tube and then back behind the engine. That rigid tube moves a bit and I assume it shouldn't. It makes it's way down between the intake manifold and the false firewall, so I can't see a thing.

Its a little grainy, but I believe that tube goes to the oil cooler on the rear of the engine.

Nice work.
