Whining sound

Hey!
Having trouble figuring out this sound. I was getting kind of a whistle or high pitched hum noise while driving. It happens when the jeep is warmed up and will only be audible when not pressing the accelerator. It sometimes is very audible and lately hasnt been as bad. I do have a coolant leak and have yet to figure out where it is. The only thing that has changed since the noise has gotten quiter, is the cooloant level. Ive added coolant to proper level after discovering the leak. Does this sound like a water pump issue?

When I read the header I thought my wife was there. With the coolant loss and sound I would be looking at the water pump.

I have the exact same problem with mine. I've changed all my pulleys, my belt is looking brand new, Checked for throttle body leaks and nothing has come up. Subscribed.

I had the same exact issue. My intake manifold wasn't properly torqued. Make sure you go through your manifold bolts and make sure they're tight. If it still happens, it might be time for a new gasket.

This.

I had this on my '02 before it was stolen. Most likely it's your intake manifold, but I was also told it could be your exhaust manifold...
