Which V6 do you have? Some have the water pump run off the timing belt, and others from the serp belt. If it is the serp belt, remove the belt and see if the noise goes away.
NOTE: If you remove the serp belt, only allow the engine to run for a few seconds, just long enough to determine if the noise is gone. If the noise goes away check all belt driven accessories for noise.
