The Cooling System is essentially a circular system that sends coolant fluid around the engine.

The water pump, driven by a drive belt, draws the coolant through the engine. As it travels it increases in temperature and pressure, before arriving at the thermostat

The thermostat opens a valve allowing the hot coolant to travel to the radiator, through the upper radiator hose. Here, it is cooled, by passing through tubes contained within the radiator. The airflow, both externally, and from the cooling fan also helps the cooling process. This fan uses a viscous coupling to keep up efficiency. However if the fan or the water pump fail, the radiator cap is a vital safety net. This valve will open, allowing the high pressure, hot coolant to escape into the expansion tanks.

The cooled coolant leaves the radiator via the lower radiator hose, and back to the water pump, where the cycle starts again.
