Like the title says; I have a high pitched noise at startup.
Jeep runs perfectly fine. Goes away after a couple of minutes.
Thoughts?

Ouch. Dunno what it is, but I'm pretty sure it ain't good. Might just be a water pump or alternator bearing.
Get yourself down to your nearest auto parts store and spring a whopping ten or twenty bucks for a mechanic's stethoscope. Start listening to different things in your engine bay, including different parts of your engine. You'll probably find the problem in a few minutes.
It's amazing what you can hear with one of those things.
But be careful! Don't listen to the battery. You'll hear things no man was ever meant to hear!

Ill deff pick one up. I know the pump is new but no history about the alt.
THe belt does screech on startup if the AC is on and I give it throttle. Could deff be in one of those pulleys.
I dont have a distributor
