The viscostatic fan clutch is a thermally controlled device that regulates the engagement of the engine cooling fan. It modulates fan speed based on radiator heat, providing maximum airflow when needed while reducing drag and noise during normal operation. A faulty clutch can cause overheating in traffic or reduce fuel efficiency and create excessive noise on the highway. We offer premium viscostatic fan clutches that deliver precise and responsive thermal control. Designed for efficient heat dissipation and quiet operation, our fan clutches ensure the engine cooling fan activates only when necessary, optimizing cooling performance while contributing to overall vehicle efficiency and driver comfort.
