The water pump uses centrifugal force to send fluid to the outside while it spins, causing fluid to be drawn from the center continuously. The inlet tothe pump is located near the center so that fluid returning from the radiator hits the pump impeller. The pump vanes fling the fluid to the outside of thepump, where it can enter the engine.
The fluid leaving the pump flows first through the engine block and cylinder head, then into the radiator for cooling again and finally back to the pump.
