用内燃機関の冷却装置。A cooling water circuit in which a radiator and a heater are connected in parallel is provided in the engine body, and a heater switching valve is installed on the engine body outlet side of the cooling water circuit to flow cooling water to the heater when the heater is on, and to flow cooling water to the radiator when the heater is off. Further, between the engine body and the heater switching valve of the cooling water circuit, the cooling water is caused to flow to the heater switching valve side that allows cooling water to flow to the radiator at a temperature T2 or lower, which is higher than the thermostat valve opening temperature T1, and the temperature is increased. A cooling device for an internal combustion engine for an automobile, characterized by being provided with a temperature switching valve that allows cooling water to flow also to a radiator at T2 or higher.
