TOYOTA TSUSHO WATER PUMP WM COROLLA/AURIS 16- PRIUS 11- 1NZ/8ZR

An automotive electronic water pump is essentially an "electrically driven centrifugal pump plus a controller." Its speed is controlled by the vehicle's ECU/VCU to drive the circulation of coolant within the cooling system. Replacing the traditional mechanical water pump directly driven by the engine belt, it serves as the "intelligent heart" of modern thermal management systems. It provides precise and controllable cooling for the engine, battery, motor, electronic controls, and turbocharger, while also supporting functions such as engine-off cooling, zoned cooling, and heater circulation. As such, it is a key actuator in modern automotive thermal management systems.
