About Electric Water Pump

1.What causes a water pump to fail?

The most common cause of water pump failure is simply from age and wear of its electric motor. Over time, most parts in a car or truck, auxiliary pumps included, start to break down due to constant wear and tear.

2.Can I drive with a broken water pump?

Heating and cooling may be affected by the vehicle. The car may begin to overheat as well. It is possible to drive your vehicle without a water pump, but not good to. Some people in the racing circuit or who drive racing vehicles purposefully remove their water pumps to obtain more horsepower to their engine.

3.What happens when water pump goes out while driving?

If the water pump goes out while driving, your car will overheat almost immediately. Without a functional water pump, your vehicle has no way to push coolant into the engine.
