The fan clutch is an important component of most belt-driven fan systems. It ensures that that the fan is engaged at low speeds or high temperatures to provide adequate airflow to your vehicle's cooling system. When sufficient airflow is present, as is usually the case when your vehicle travels at high speeds, the clutch will disengage the fan to save on power, removing that additional load from your engine so that it may run more efficiently.

A thermal fan clutch relies on a thermostatic coil to read the under-hood temperature. When the temperature reaches a set level, the fan will engage to provide additional airflow for the cooling system. If the temperature drops to a set level, the fan will then disengage to save on power and decrease the load against the engine, thus allowing your vehicle to run more efficiently.
