Furthermore, the pump is driven by an auxiliary belt from the crankshaft pulley.

A water pump consists of impeller blades. The impeller blades and centrifugal force produce a force. The effect is used to move the cooled water into the engine of the car. The cooled water might also flow through the water jacket. The water jacket is situated near the combustion chamber.
