Jeep Whining/Whistling Noise?

Hey all

My Jeep just got serviced all fluids flushed and radiator replaced.

Everything was fine until today, a whistling/whirring/whining noise popped up in my engine.

It is not intake manifolds (just cranked them as tight as i could) or a belt, brand new belt just put on and checked.

What could it be?

If it was just serviced, I would take it right back to the shop and have them recheck every thing they touched.

If you had it done at a dealership, talk to the service manager and take them for a ride.

How's your voltage? I've had alternators make a whine when going bad.
