Whistle sound only when cold!

Sounds like a vacuum leak to me. Hard to tell where it's coming from but you could always start it and spray all of your vacuum connections with something like brake cleaner or WD40 and if you hit the leaking area, the engine speed will change because it's sucking in the spray. Also try spraying around the throttle body and the intake where it meets the head. Good luck!

if it was from vacuum shouldn't it have caused the engine to idle strange when it happened?as far as i remember the idle was ok when it happened and i was stopped and hearing it.also the fact that i could have heard it today allthough i stopped and idled does it mean that it has nothing to do with the trans or the front drive shaft?also i'm almost sure that the whistle wasn't coming from the pulleys or serpentine belt.any ideas guys??

I've noticed the same thing recently, and only when it's cold outside. Will be investigating over new years and let you know if I find anything...

Has anyone actually figured out what this is yet? I'm having this problem on my 2004 Grand Cherokee Laredo and I would like to find out what it is since this is my daily vehicle.

I am curious what the deal is with this too. When it gets really cold (basically anything below zero) my Jeep makes all sorts of wierd noises. It makes a whistleing sound, it idles rough, and the engine itself sounds louder out of the exhaust. But it only does this when it is cold. As soon as it warms up the jeep drives normally again. I have taken it to the dealership twice in the past two years for this kind of stuff and they just keep telling me that it is normal.

Well nothing yet from me!What i can tell you though is that if i don't give it too much gas and i drive slowly until it heats up well it doesn't make that whistling sound.What worries me though is that the last time i heard this whistling sounds from my engine bay was when i changed my driving belt 9 months ago and after a while the pulley exploded and i was lucky that no more damage happened to the engine cause i was just starting the jeep when it happend.After i changed my pulley with a new one i had no sounds but after the first cold days they begane again!I don't believe they are related though...PS:talking about strange sounds, the door buzzer comes on sometimes without a reason for a couple minutes and then just goes away!!

I have a whistle too, almost sounds like a turbo spooling. I THINK it might be an exhaust leak. It usually goes away within 2-3 minutes.

I wish it were a turbo, between that and my throttle body spacer whistling, I feel like I should be really fast.

This whistle only seems to happen when I let off the gas and when I park in my garage (engine at idle speed). Once I give it gas, it goes away, but when it returns to idle, it whistles. Appears to be coming from the rear of the engine bay down low (tranny area).

well, there isn't much i can tell you until i know where it is coming from. the best way i found to figure out where a noise is coming from is to unscrew an old wooden rod from a broom. while the engine is on and making the noise put one end of the pole on a spot of the motor then your ear up to the other end. keep moving it around until you hear it the loudest. then you should be able to pinpoint the problem.

PS. allot of the time in the cold your belt makes allot of noise. if it is your belt the sound will become higher as the engine revs. Good Luck, and be careful with the pole
