An engine cooling system (2) includes a first passage (11) communicating a radiator (8) with a jacket inlet (7) of a water jacket of an engine, a second passage (13) communicating a jacket outlet (12)of the water jacket with the radiator, and a third passage (16) communicating a part of the second passage with a part of the first passage located between the radiator and the water pump. To allow the cooling water temperature circulating in a water jacket of an engine to be detected accurately, a water temperature sensor (72) is provided in a part of the second passage intermediate between thepart of the second passage where the third passage branches off and the jacket outlet. 本发明涉及用于内燃机的冷却系统。种发动机冷却系统(2)包括：第通道(11)，其将散热器(8)与发动机的水套的套入口(7)连通；第二通道(13)，其将所述水套的套出口(12)与所述散热器连通；以及第三通道(16)，其将所述第二通道的部分与所述第通道的位于所述散热器和所述水泵之间的部分连通。为了允许准确地检测发动机水套中循环的冷却水温度，水温传感器(72)设置在所述第二通道的位于所述套出口和分支有所述第三通道的所述第二通道的部分中间的部分中。
