It might not be the water pump. If you are handy with tools, remove your serpentine belt and start the engine. If the sound goes away, it's either the tension pulley, power steering pump or alternator. If the sound is still there, remove the AC belt. The AC clutch or tension pulley could be bad. Restart engine. If the noise is still there, it is either the water pump or tensioner pulley. If you have to change your water pump, do it right and change the belt, pulley and maybe the tensioner since everything is right there when you open her up. Also, an automotive stethescope helps find sources of noise.
