Hello, When I first start my car and in the first five to ten minutes of driving I am hearing a chirping or trilling coming from the right side of the engine compartment or the wheel well. I occurs when I am idling on and off, and when I am trying to accelerate, brake, or turn. But only for a few minutes then it stops. What is up?

That is a common description of a belt squeal. It can be caused by a weak spring-loaded tension-er pulley, small rocks or dirt embedded in the belt, or a pulley that is tipped or turned due to a worn bearing or broken bracket. To verify it is belt noise, open the hood with the engine running, then dribble a little water on the smooth backside of the belt. If the belt is the cause, the noise will change noticeably.
