ACTIVE COOLANT MONITORING AND LEAK MITIGATION IN VEHICLE COOLING SYSTEMS

Abstract: a vehicle cooling system includes a heat exchanger, upper and lower coolant hoses extending between the heat exchanger and a vehicle power system for carrying liquid coolant to and from the vehicle power system, and an expansion tank fluidly coupled to the lower coolant hose. the vehicle cooling system further includes an active coolant monitoring system that includes a coolant leak sensor that detects leakage of the liquid coolant from the vehicle cooling system and a coolant contamination sensor that detects contamination of the of liquid coolant. the vehicle cooling system further includes an electronically controllable coolant flow shutoff valve in series with the lower coolant hose adjacent a lower coolant outlet of the heat exchanger. the electronically controllable coolant flow shutoff valve is closed when the coolant pump is off and open when the coolant pump is on.
