Abstract:
A cooling device for an engine includes a radiator route passing through a radiator, that are merged together after being branched on the downstream side from the inside of the engine in a coolant circuit configured to allow a coolant to flow from a pump through the inside of the engine and return to the pump. An at-stop control section provided in the cooling device controls a multiway valve that has three discharge ports, including a radiator port connected to the radiator route, so as to close the radiator port and open at least one of the other discharge ports when an ignition switch is turned off.
