Water pumps fail due to a bad bearing and/or shaft seal. Look at the bottom of the pump. There is a drain hole in the casting below the shaft. If the seal is bad then coolant will be leaking out of this hole.

How do you tell if the water pump is going out on a 2000 Ford Taurus?
You can tell by if there is a leak around the pumps impeller or the gasket. If there is a leak, then the water pump would need to be changed. Secondly if there is no pressure in the cooling system, vehicle is overheating. Chances are the impeller inside the pump is melted, the water pump would need to be changed. Last, if the bearing are worn out on the water pump which would cause unusual noise would be an indication for the pump to be changed.
