High pitched sound
I have a high pitched sound coming from under my hood. The first 10-20 minutes I drive from a cold start is when I hear it and only when I let my foot off the gas. When I accelerate the sound goes away. I thought it might me a ground but when I roll down my window the sound is even louder. It's coming from my hood but I can't find the cause.

Is the belt tight and in good condition?

The belt is brand new and was changed after the high pitched sound began. I brought it Jeep and they a hole in my radiator was spraying on my belt was causing the sound. Their idiots. I did get a new radiator for free though.

Check for vacuum leaks. When you let off the gas the mainifold vacuum will increase, and amplify any vacuum noises.
