A vehicle's water pump is a belt-driven pump that derives its power from the crankshaft of the engine. Designed as a centrifuge, the water pump draws cooled fluid from the radiator in through the pump's center inlet. It then circulates the fluid outward into the engine and back into the car's cooling system.

How does an engine water pump work?

The water pump is a simple centrifugal pump driven by a belt connected to the crankshaft of the engine. The pump circulates fluid whenever the engine is running. The water pump uses centrifugal force to send fluid to the outside while it spins, causing fluid to be drawn from the center continuously.

Can an engine run without a 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.
