PROBLEM TO BE SOLVED: To provide a cooling device for a vehicular internal combustion engine that enables suppression of deterioration of cooling performance of a vehicle while the internal combustion engine is automatically stopped.SOLUTION: A cooling device for circulating cooling liquid in a vehicular internal combustion engine by using an electric water pump includes a heater core cooling liquid line for supplying cooling liquid to a heater core of an air conditioner of the vehicle. When the electric water pump is operated to circulate the cooling liquid with the internal combustion engine automatically stopped, as a level of a heating request for reheating by the heater core air-conditioned air that has been cooled by a cooling unit of the air conditioner is lower, supply amount of the cooling liquid to the heater core cooling liquid line is reduced.

    【課題】内燃機関の自動停止状態において、車両の冷房性能の低下を抑制できる、車両用内燃機関の冷却装置を提供する。【解決手段】冷却液を電動式ウォータポンプによって車両用内燃機関に循環させる冷却装置において、車両の空調装置のヒータコアに冷却液を供給するヒータコア冷却液ラインを備え、内燃機関の自動停止状態において電動式ウォータポンプを動作させて冷却液を循環させるときに、空調装置の冷却ユニットで冷却された空調空気をヒータコアで再加熱する加熱要求が低いほど、ヒータコア冷却液ラインへの冷却液の供給量を減少させる。【選択図】図4
