ABSTRACT:
A down flow, two tank, two pass radiator includes a flow division baffle in the center of the upper tank that automatically vents any air trapped behind the baffle as the engine operates. When the engine starts, colder coolant has contracted a thermo wax operated baffle slide to an open position, allowing any trapped air to vent through. As the engine and coolant warm to normal operating temperature, the wax expands, pushes the slide closed, and the baffle operates as a solid piece.
