Hey guys,

I've recently noticed a god-awful noise coming from under my hood when I first start my car. It is a combination of a whining and whistling noise. The noise happens only when the car is first started and once it is warmed up the noise will come back when I get around 2,700 rpm then go away shortly after I shift. The only 2 things that have changed since this has happened were the installation of a cold air intake and this awful cold weather (single digits here in Cincinnati).

any ideas?

 

CAI's can sometimes make a whistling noise because you no longer have a resonator. I like my trusty JDM airbox with a drop-in K&N.

 

Yea, I've grown used to that noise, but this noise is obtrusive...kind of sounds like a belt but with some more air sounds to it...I am lost.

thanks for the ideas!

 

Every winter when it gets this cold (It was -8 yesterday) my engine tries it's best to scare the **** out of me. A high-pitched grinding/scraping sound that goes away once the car warms up. Hopefully this year will the same as the last 10 years, and magically heal itself with warmer weather.

 

Kinda sounds like what is going on with me. I'm scared half to death, haha.
