When I start my Jeep up it makes a weird howling sound. At first I thought it was a whistle, and I decided to leave it alone. Then I noticed that it is RPM dependent. When I rev it higher than usual it really starts to squeal, it almost sounds like a supercharger whine you would hear from a Dodge Demon. After 20-30 minutes the sound is gone, so I feel like after the engine gets properly warmed up it starts to calm down. At this point don’t know if I should be worried or not, so I’ve just turned the radio up to drown it out.

Is anything broken?

Should I be worried?

If I haven’t explained it well enough I’ll take a video and see if I can clip it to the post.

Thanks as always!
 
I'd check for werewolves! I had one under the hood of an old Chevy.
Or it could be something in the serpentine drive. Seemed like the werewolf left when I changed out the power steering pump.
