A branch portleading to the delivery pipeto the heater core is opened in an upper portion in the central passagein a state where the coolant passage deviceis mounted to the engine, and the branch porthas a wall surfacesurrounding the branch port and hanging down into the central passage. The wall surfaceprevents bubbles contained in the coolant from entering the branch port. And the coolant passage device consequently prevents coolant flow noise from occurring.
