Behr’s Visco technology for engine coolant pumps is designed to reduce parasitic power losses that affect fuel economy. The electronically controlled system varies coolant pump speeds based on engine requirements and operating conditions by isolating engine input speeds hydraulically and minimizing power consumption under high-speed operation and light-engine loads where maximum flow rates are not required.
The pump’s control logic is embedded in an engine control module. The coolant pump is designed for the life of the vehicle and does not require periodic maintenance. For more information, go to www.behrgroup.com.
