PURPOSE:To hold cooling fluid to a fixed condition in no relation to an operational condition and weather condition, by dividing a radiator into two chambers and using only one or both of the chambers to cool the cooling fluid in accordance with cooling fluid outlet temperature of the radiator. CONSTITUTION:Cooling fluid fed into a water jacket of an engine 1 by a cooling fluid pump 5 is circulated via a cooling fluid outlet part 1A, conduction pipe 4, radiator 13, radiator outlet 13C and conduction pipe 6. The first thermostat 2 is provided to the part 1A, at low temperature of the cooling fluid, the part 1A is closed to flow the cooling fluid in a bypass pipe 17. While the radiator 13 is divided into the first chamber 13A and the second chamber 13B by a separator wall 14, and the second thermostat 16 is provided in the vicinity of the outlet 13C of the wall 14 to cool the cooling fluid only by the chamber 13A at prescribed temperature or less. |
