Horton has introduced the VMaster Ultra fan drive, designed to cool the higher-horsepower, hotter-running '07-compliant engines. The direct-controlled viscous unit is managed by the engine's ECU.
An integral fan speed sensor provides closed-loop control, and the “optimized magnetic design speeds up reaction time for better modulation and cooling,” according to Horton. In addition, the reservoir, actuator and valve system combine to deliver a lower off-speed and faster response time resulting in optimum cooling, reduced fan noise and increased fuel efficiency, the company reports.
Other features of the VMaster Ultra include a rear-mounted cable harness to shield the connection from fan blades and installation on the front of the fan drive to increase airflow.
