What causes damage to the water pump?

A. Antifreeze gels and water hardness, due to their chemical composition, are very gritty. Think of them as liquid sandpaper. As they pass through the working parts of the water pump, they erode the impeller, which can contribute to increased operating temperatures due to decreased coolant flow. Eventually the gels make their way to the seals of the water pump, causing leaks and water pump failure.
