What does a fan clutch have to do with AC?

The fan clutch is an automatic device that is frequently used in a vehicle’s cooling system. Thus, when the engine is cool or even when it is at a normal operating temperature, the fan clutch will disengage the engine’s radiator cooling fan to a certain degree (which is mechanically compelled).

What does a bad radiator fan sound like?
