PROBLEM TO BE SOLVED: To provide an engine cooling device capable of appropriately restricting lowering of heater performance. SOLUTION: This engine cooling device has a plurality of circulation circuits for circulating the cooling water, and this engine cooling device is provided with a heat storage vessel 15, a heater core 13, and a three-way valve 22. As the cooling water circulation circuits, a heater closing circuit for circulating the cooling water through the heat storage container 15 and the heater core 13 without passing through an engine E and a heater circuit for circulating the cooling water through the engine E and the heater core 13 without passing through the heat storage container 15 are included. When heating is requested over from a start of the engine E to the warm-up operation, the cooling water is circulated through the heater closing circuit, and when temperature of the cooling water for cooling the engine E becomes higher than the temperature of the cooling water circulating in the heater closing circuit, circulation of the cooling water in the heater closing circuit is stopped, and while the cooling water is circulated through the heater circuit.
