The fan is set up to augment the natural air flow that occurs during vehicle
movement. The fact that the air pulled through the radiator by the fan will
then impinge on the engine is strictly collateral. In essence, the radiator is
positioned in the front of the engine bay to take advantage of the airflow
resulting from the forward movement of the car. The fan is mounted behind the
radiator on the front engine where driving it with a belt is most convenient.
It was not the intent to try to cool the engine directly. It doesn't work
very well anyway.
