Screechin noise
For those of you who live where its extremely cold. Do your jeeps make a kind of screeching sound in the engine bay when you turn the car on after leaving it over night? Mine does this and its extremely loud. i dont know if its normal or what. I do have a video of it tho and you can clearly hear it.

Re: Screechin noise

Re: Screechin noise
belts are probably slipping.

Re: Screechin noise
Its got 28k miles but this only happens when it sits over night in below 20 degree weather and only on the first time i start it up for the day.

Re: Screechin noise
How long does the screeching last for? Just check your belt. By checking it looking for cracks in the belt. Just check that. Don't freak out if you find them I just want to know. If there are tell me if you see big or small cracks.

Re: Screechin noise
Its only a second or two. Too cold too check now lol Soon as it revs up on start up is when it does it. after that i can leave it sitting there for hours and start it up again and it wont do it. Its like a one per day kinda thing

Re: Screechin noise
Hmmm....Do you let it warm up every time you start it? Possibly your Serpentine belt is slipping. You only here it when you stat up the car for the first time in the morning right?

EDIT: I don't know if you would remember this but next time before starting the engine look for any Liquids on the belt.

Re: Screechin noise

Re: Screechin noise
The cold is making my Jeep screech as well, sounds like my rear links - never heard anything until today it was below zero for most of the morning and then again single digits on the drive home. Nothing from the engine bay yet.
