  Here are the stages:
  Water flows around the engine. The engine is cooled and the water is heated.
  The hot water enters the radiator through the top hose.
  It flows down through the radiator. Here it is cooled by air.
  The cool water leaves the radiator through the bottom hose.
  The water is pumped around the engine again.
