If the pump is blowing breakes, there is probably a short in the pump. The well could also be ceased. If there is very little water being pumped, the well could be dry or the pump might be "shot"

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.

If a water pump is bad they usually leak coolant
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.
