Equipped with electronically controlled Visco system, Engine Coolant Pumps maximize fuel economy savings for heavy trucks. Visco technology covers variable-speed, fuel-saving air- and coolant-flow products by hydraulically isolating engine-input speeds and minimizing power consumption under high-speed operation and light engine loads where maximum flow rates are not required. Designed for life of vehicle, Visco coolant pumps do not require periodic maintenance.
