Fan Blade Operation:
In an engine cooling-system the fan blades pull the air through the radiator core and over the engine to remove heat. A fan belt or an electric motor usually drives the fan. Conventional belt driven fans can rotate continuously (sometimes called Flex Fan) while others are controlled by thermostatic/centrifugal clutches. Some electric fans are pull fans and some (which mount on the front of the radiator) are push fans.
How To Instructions:
- Check for obvious problems.
- Out with the old, in with the new.
