Alternator maybe? Whining while its charging? If you can get it to do it while idling use a mechanic's stethoscope to listen to each component of the front accessory drive to determine what it is. You can also use a piece of pipe or long screwdriver but it's not as good. Watch out for the fan!😱

Jared has a great suggestion with the mechanics stethoscope.

Does it whine while driving or just sitting still running or both?

It does do it when idling and at times when I drive but wjen its idling it gets pretty bad and alternator tested and checked out fine...

But both...mechanic did a quick once over and sounds like water pump but not 100% certain considering he was busy

Long screwdriver or metal rod works as a stethoscope. Disconnect plug on alternator and see if noise goes away

Could be water pump or alternator. Bearings in those. As suggested use a stethoscope or a long screwdriver. Sometimes you can just put it on those a feel that somethings not right. Been my experience, but I guess not always, when water pump bearing goes out it leaks out of very small hole on bottom of water pump. And belts are adjusted properly as you have stated? Got to be a moving part. Power steering pump? Btw, what kind of motor?

try taking the alt belt off and see if is goes away. provided you have other belts to drive the water pump.
