    Got a new noise coming from the engine bay. Sounds like a chirping/whistle on acceleration. I had my truck idling for a few minutes and then it Started making this noise. Any ideas? The belt or pulleys?

    Serpentine belt, or idler pulley. Spray a little water on belt, see if it goes away.

    Usually water will make it quieter. Get new serpentine belt. Spin idler/tension pulleys by hand. See/hear if they spin freely/ smoothly.
