Visctronic fan drives utilize BorgWarner’s proven viscous technology with precise electronic control. The fan drive is controlled by the engine’s control module for precise fan speed modulation. Visctronic fan drives provide better engine cooling and improved fuel economy with minimum parasitic loss. The Visctronic fan drive’s ability to better control engine temperature effectively provides the cooling needed for low tailpipe emission requirements and lowers average fan speed and horsepower during cooling resulting in lower noise, greater economy, and improved driver comfort. All of which make it an ideal choice for passenger car, sport utility vehicles (SUVs), and light trucks around the world.
