4. Water Pump :
The water pump is a simple centrifugal
pump driven by belt. The pump circulates the
engine coolant when it is driven by the
engine.
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 to the pump is located
near the center so that fluid returning from the
radiator hits the pump vanes. The pump
vanes filling the fluid to the outside of the
pump, where it can enter the engine.
The fluid leaving the pump flows first
through the engine block and cylinder head,
then into the radiator and finally back to the
pump.
