Hey guys, right after i crank the engine or when im idle, i hear this "whistiling" noise comming from my engine bay. Its not really loud and it seemed to start when it started getting cool outside. And it will go away after the engine gets warm.Is there anything i especially need to do to the car for the winter?

 

Well, is it TII or N/A? If it just started doing it cold, its probably not a bad thing because its sucking in cool, dense air and it is very happy. Also, are you sure its your engine and not your throw out bearing whining? If it does it in neutral with the clutch out, its probably either the throw out bearing or the input shaft. If thats the case, no problem.
