Thermal Fan Clutches operate in response to underhood temperatures. When the engine is cold, the fan is disconnected; when too much heat is generated,
the fan is allowed to cool the engine. A bi-metal thermostatic coil mounted at the front of the clutch senses the underhood temperature
and operates the clutch accordingly.
