Abstract
A U flow radiator with a header tank split into inlet and outlet sides I and O by a lengthwise divider wall has a coolant inlet consisting of a cylindrical pipe . A hollow cylindrical barrel co extensive and coaxial with pipe and extending across divider wall , with cut outs and opening respectively into both sides I and O. A thin walled, hollow cylindrical sleeve turns within barrel with windows and that alternately block or open the cut outs and , or open both partially. A rotary actuator turns sleeve within barrel . Coolant can be selectively routed all to the tank outlet side O, by passing the radiator for quick warm up. After warm up, coolant can be routed to I or O in desired proportions to increase or decrease cooling capacity. With high engine cooling demand, all coolant is routed to the inlet side I and all coolant passes through radiator
