The main casting bodyincludes a plurality of cylindrical plug hole wallswhich have plug holesformed therein inside a head-side water jacket. The cylinder head also includes partitions, formed inside the head-side water jacket, and these partitions connect the plug hole wallstogether form a dividing wall, which divides the water jacket into an exhaust port section and an intake port section. Coolant entering the water jacket is divided into two substreams, which flow initially in substantially opposite directions, and which are reunited after flowing around opposite ends of the dividing wall.
