What temperature is the fan clutch on ?

[@hortoninc]

Hi Leonel! Good question.
The temperature that the fan clutch engages varies from application to application. The truck's ECM manages the cooling requirements (charge air cooler, radiator, AC condenser, etc.) and engages the fan clutch when it’s time to cool.
