Abstract: A method for controlling an internal combustion engine cooling system includes pumping coolant in an engine cooling loop with a coolant pump, pumping the coolant in an air cooler loop that includes a liquid-to-liquid heat exchanger with the coolant pump, and receiving a condition signal indicative of at least one condition associated with the internal combustion engine. The method also includes, based on the condition signal, adjusting a position of a flow control valve to modify a flow of coolant to the liquid-to-liquid heat exchanger.

Abstract: A cooling system includes an internal combustion engine, a coolant pump in fluid communication with the internal combustion engine, and a liquid-to-liquid heat exchanger configured to receive coolant from the internal combustion engine via the coolant pump. The cooling system also includes a bypass valve connected downstream of the coolant pump, the bypass valve configured to close a fluid path that connects the coolant pump and the liquid-to-liquid heat exchanger.
