Whining noise coming from engine

I have an 01 tj and recently a whining noise started to come from somewhere under the hood.
I looked on here to see if anyone else had the same problem but all the threads were about whining noises when turning or coming from a wheel.
My noise is not from one of those, I can here it when the car is on but parked.

When I first start up from cold, going to school in the morning, there is no noise. But by the time I get there you can here it. It sounds like its coming from the back left part of the engine(if you were sitting in the car listening). Pretty much right behind the steering wheel but in the engine compartment.

Any idea what this could be?

have you checked your power steering pump?
im having similar issues in my 4.7 WJ and it turned out (after replacing belts, alternator, and some pulleys) that the power steering pump is on its way out.

Sorry, I'm not much of a mechanic guy
Try to revolve your engine and keep it at a constant RPM and turn your steering sharp left and sharp right, if the whining tone changes while u r turning the steering, that is a good indicator shows that your whining noise is Coming from the PS pump, but check the fluid first, may be the level is low or the type of fluid is incorrect or your hose is leaking.

By the way, the procedures above should be done while your car is stopped on Neutral

i had the pulleys go and were whining and grinding. get a great big screwdriver and put the handle in your ear and the tip on different places. use it as a stethescope. seriously. youll be able to tell on something going as long as you can touch it

Turns out it was an evap hose. The previous owner, instead of getting the proper hose, took a rubber tube and used it as a hose. The side wall wasn't strong enough and it ended up collapsing in on itself while operating, causing the whining noise.

The power steering pump does make what seems to me to be an odd sound when turning. Although this is my first jeep so that might just be how they sound.
