Learning Objectives:
• Recognize the purpose and advantages of a fan drive.
When engaged, the fan drive activates the fan to cool the engine by pulling air through the radiator. Depending on the size and rotational speed of the fan, as much as 70-100 Hp may be needed to run the fan. The fan drive engages only when needed resulting in additional horsepower for drive axles, less noise, and increased fuel economy. Due to these benefits, most new diesel powered vehicles are equipped with a Horton On/Off fan drive.

NOTE:
 An engaged fan drive pulls air through the radiator to cool the engine.
