Abstract
The present disclosure provides an engine cooling system for controlling the temperature of an engine of a motor vehicle. The system includes an engine cooling circuit for circulating a coolant to transfer heat from the engine to an airflow. An electric water pump is configured to circulate the coolant through the circuit at a maximum electric pump flow rate, and a mechanical water pump is configured to circulate the coolant through the circuit at a maximum mechanical pump flow rate that is higher than the maximum electric pump flow rate. The circuit further includes a selector valve configured to fluidly connect one of the electric water pump and the mechanical water pump to the engine. An engine control module generates a valve signal for actuating the selector valve to fluidly connect one of the electric water pump and the mechanical water pump to the engine.
