PROBLEM TO BE SOLVED: To provide a cooling device of an engine, efficiently recovering high-temperature refrigerant into a heat storage receptacle. SOLUTION: This cooling device of an engine is provided with a cooling circuit including: a radiator passage for causing cooling water flowing out of the engine E to flow into the engine E through a radiator 12; a bypass passage for causing the cooling water flowing out of the engine E to flow into the engine E not through the radiator; and a flow control valve 22 for controlling the flow rate of cooling water circulating through the bypass passage, and a heat storage passage having the heat storage receptacle 16 storing the cooling water in the thermal insulating state and selectively connected to the cooling circuit to constitute a heat storage circuit. After warm-up of the engine E, the flow control valve 22 is opened to circulate the cooling water flowing out of the engine E to the bypass passage. When the temperature of the cooling water flowing out of the engine E is a predetermined temperature or higher, the flow control valve 22 is closed so that the cooling water flows into the heat storage receptacle 16.
