Sound under the hood

What does this sound like? I have checked my fluids and they are good. The belts are good. This squealing sound only happens when the Jeep is idling. It's a 97 TJ. Thanks

Sounds like valvetrain a bit. Get one of these to isolate the sound.

I don't think its valvetrain.
Sounds like the belt. I just had this same thing last week. Turns out the belt was too tight and the alternator was going out. Water and steering and AC when they start to have bearing issues do that too.
Does it go away after a few minutes? If it does then its more than likely alternator.
If you gave it tested take it out to gave it tested that way you can check the bearing.
