Excessive tension on a fan belt or serpentine belt also can overload the water-pump shaft bearings and cause the pump to fail. But in most instances, water pumps fail because of shaft leaks.

What causes electric water pump failure?

Using the wrong coolant Just as with standard water pumps, the use of general, over-the-counter coolant when coolant with specific properties is prescribed can cause the premature failure of electric water pumps – as does mixing coolants with different chemical components or using contaminated coolant.

Why is my car overheating with a new water pump?
