たことを特徴とするエンジンの冷却装置。 The engine coolant outlet and the radiator coolant inlet are connected by a coolant outlet passage, and the engine coolant inlet and the radiator coolant outlet are connected by a coolant inlet passage equipped with a thermostat that opens and closes depending on the coolant temperature. At the same time, the cooling water outlet and the thermostat are connected by a bypass passage that bypasses the radiator, and when the cooling water temperature is higher than the set value, the thermostat is opened to allow cooling water to flow to the radiator and set. If the temperature is below this value, the thermostat is closed to allow the cooling water to flow back to the engine side without passing through the radiator, and the cooling water outlet of the engine and the cooling water inlet of the heater are connected through a heater inlet passage. At the same time, the cooling water outlet of the heater is connected to a position downstream of the thermostat of the cooling water inlet passage through the heater outlet passage, so that cooling water is continuously supplied to the heater during engine operation. 1. A cooling device for an engine, characterized in that a branch passage branching from the heater outlet passage is connected to the thermostat.
