2002 Chevy S10 with 100K miles.
Whistleing noise intermittently coming from engine bay on cold idle. With rpms up, whistle goes away.
I'm having difficulty locating the noise.
Thoughts?

Can you narrow down the sound to any particular area? Does it change with RPM? Does it stop immediately or after a few seconds when you shut it off? You could try removing the serpentine belt temporarily to help narrow it down.
