PROBLEM TO BE SOLVED: To provide a vehicular cooling system capable of realizing suitable cooling efficiency of a heat exchanger regardless of a vehicle speed. SOLUTION: This vehicular cooling system has the heat exchanger 1 mounted on a vehicle front part, a cross-flow fan 2 arranged on the vehicle rear (or front) side of the heat exchanger 1 and a shroud 3 forming an air flow passage up to the cross-flow fan 2 from the heat exchanger 1, and cools the heat exchanger 1 by a traveling wind of a vehicle and/or cooling air generated by driving of the cross-flow fan, and is characterized in that a heat radiating surface of the heat exchanger 1 is divided into two parts of a high part and a low part of a hear radiation rate, and a freely openable-closable opening-closing part 3a is arranged in the shroud 3, and when opening an inside space of the shroud 3 to an outside space by the opening-closing part 3a, the high part of the heat radiation rate of the heat radiating surface faces a flow passage communicating with the cross-flow fan 2, and the low part of the heat radiation rate of the heat radiating surface faces a flow passage communicating with the outside space of the shroud 3.
