power steering fluid???

Re: weird noise

Get a length of hose or a mechanic's stethoscope and listen to each pulley to isolate the problem.

that noise is somewhat normal for the 3800 engine

Alternator bearings can sound like a jet which sounds cool

Re: weird noise

is it a squeak or a howl?

a squeak would be a pulley, unless its SHOT. a howl would be more of a power steering issue. does it do it more when you turn your steering wheel? or just makes noises regardless..

I guess with the new belt being on putting more strain on the pulleys. try doing what ROB BELL said... but move your steering wheel or have someone do it and listen...

if push comes to shove, you can do a process of elimination. spray a little WD-40 on one pulley at a time (behind). and see if the squeak stops. Just a thought.

Re: weird noise

Alternators tend to make a whistling kind of whine on cooler or moist days. Also check power steering fluid level, check for any stiff pulleys, etc.

Mine sounded like that before my tensioner pulley went out.

Re: weird noise

well im guess its like a supercharger sound i can hear it when i gun it like at 3000 rpm i was thinking it was the alt pulley but i cant seem to find that pulley anywhere but my car never usto do that sound till a month ago it sounds nice but getting annoying

Re: weird noise

Like others on here, mine has always had a faint, high-pitched whine, like a turbo. So I don't worry about it, I just enjoy the sound. But if your whine suddenly started out of nowhere, look into it quickly before something fails and leaves you stranded.
