Sounds like you need a water pump, The bearings in the water pump are making the noise not the pulley.
The bearing is on its way out. Replace the pump soon.
The pump will need replaced if it is grinding.
A bad bearing in the water pump could be one possibility.
It sounds like a loud bearing going out in a pump. The noise comes from the engine department.
When it starts leaking are making noise.
If it is leaking antifreeze or water, or if it is making noise or binding when turned by hand.
repace the fan belt that drives the a/c unit. If it doesn't fix it, it's the a/c pump. Very costly. Live with the noise.
Bearing in: Alternator? Water pump? A/C Compressor? Belt tensioner?
if it is not making any noise,or leaking from bottom of pump. Releif hole is on bottom of pump,if leaking replace pump.
if the noise is a high pitched squealing noise, the belt is slipping....if the noise is a whine or growling noise, the pump is low on fluid or the pump is bad
