Properly called a coolant circulation pump, the water pump pushes the coolant through the cooling system. The water pump is driven by a shaft that protrudes out of the front of the water pump. Some vehicles have a secondary water pump which is electrically driven. An internal seal keeps the coolant from leaking past the shaft. However, sooner or later the shaft bearings will fail or the shaft seal will leak. Dirty coolant makes the seal wear out sooner. Some water pumps are driven by the Timing Belt making their replacement somewhat costly. Keeping the coolant clean helps to extend the life of the water pump.
