Beschreibung
Zusammenfassung:	Provided is an engine cooling apparatus capable of preventing deterioration in reliability of a cylinder head of an engine during cold engine operation. The engine cooling apparatus comprises an engine cooling water path, a heater core cooling path, and a radiator cooling water path, and further comprises a switching valve for switching among these cooling water paths. The switching valve is operable, when the temperature of an area around an exhaust valve is raised to a value greater than, e.g., 150° C., even in a situation where the temperature of cooling water for cooling the engine is equal to or less than, e.g., 50° C., to switch from the in-engine cooling water path to the heater core cooling water path.
