An engine cooling device for a vehicle of the present invention includes: 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 switching section 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 control section that, in a case in which an ignition switch is turned off, controls the switching section such that the communicating state is set.
