Hayden fan clutches are manufactured in an ISO 9001-certified facility and tested to ensure they match original equipment performance. When the engine is cold, the fan clutch disengages to provide quieter operation and better fuel economy. As underhood temperatures rise, the thermal spring activates the clutch to provide increased airflow through the radiator for optimal cooling performance.
