Engine cooling device for vehicle

An engine cooling device for a vehicle comprising:

• an engine cooling circuit that circulates a cooling liquid to an engine and a heat exchanger;
• a reservoir tank that is connected to the engine cooling circuit, and that stores the cooling liquid to absorb pressure changes within the engine cooling circuit;
• at least one or more cooling liquid circulating circuits that circulates the cooling liquid to devices installed in the vehicle;
• a switch that selectively switches between either of a communicating state of communicating the engine cooling circuit and the cooling liquid circulating circuit, and a cut-off state of cutting-off the engine cooling circuit and the cooling liquid circulating circuit;
• and
• a controller that, in a case in which an ignition switch is turned off, controls the switch such that the communicating state is set, wherein
• in the cut-off state, each of the cooling liquid circulating circuits circulates the cooling liquid within the each of the cooling liquid circulating circuits and the cooling liquid is kept from reaching the engine and the heat exchanger in the engine cooling circuit.
