ンジンの冷却装置。 In an overhead valve type engine that has an exhaust push rod hole into which an exhaust valve drive push rod is inserted on the side where the exhaust port is provided with respect to the cylinder row, cooling is provided in the area between the valves where the intake port and exhaust port are close to each other. An intervalve cooling water hole for supplying water is drilled to intersect with the exhaust push rod hole, and a guide sleeve is attached to the exhaust push rod hole to form a cooling water introduction gap communicating with the intervalve cooling water hole on the outer periphery. An engine cooling system characterized by:
