A U flow radiator 10 with a header tank 12 split into inlet and outlet sides I and O by a lengthwise divider wall 18 has a coolant inlet consisting of a cylindrical pipe 22 . A hollow cylindrical barrel 24 co extensive and coaxial with pipe 22 and extending across divider wall 18 , with cut outs 26 and 28 opening respectively into both sides I and O. A thin walled, hollow cylindrical sleeve 30 turns within barrel 24 with windows 36 and 38 that alternately block or open the cut outs 26 and 28 , or open both partially. A rotary actuator 40 turns sleeve 30 within barrel 24 . Coolant can be selectively routed all to the tank outlet side O, by passing the radiator 10 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 10.

1. A radiator 10 having a U flow coolant flow pattern with a header tank 12 divided into an inlet side I and an outlet side O by a central dividing wall 18 and an opposed return tank 14 , said header tank 12 further having a cylindrical pipe inlet 22 through which inlet coolant flows, characterized in that a low pressure drop coolant flow control valve is integrated into said header tank 12 , comprising,a cylindrical barrel 24 co extensive with said pipe inlet 22 and extending within said header tank 12 across said divider wall 18 , said barrel 24 having cut outs 26 , 28 opening into each of said header tank inlet sides I and O respectively,a hollow cylindrical sleeve 30 that fits closely within barrel 24 , having an open end 32 that is concentric to inlet pipe 22 so that coolant entering inlet pipe 22 enters the hollow interior of sleeve 30 with substantially no additional restriction, and a pair of windows 36 , 38 alignable with said barrel cut outs 26 , 28 respectively so as to alternately open or block said cut outs 26 and 28 , or to partially open both cut outs 26 and 28 ,and actuator means 40 to move sleeve 30 within barrel 24 so as to selectively align said respective cut outs 26 , 28 and windows 36 , 38 , thereby opening inlet pipe 22 only to header tank inlet side I, or only to header tank outlet side O, or partially to both sides I and O. 2. A radiator 10 and integrated flow control valve according to claim 1, further characterized in that said actuator means 40 is a rotary actuator that turns sleeve 30 within barrel 24 . 3. A radiator 10 and integrated flow control valve according to claim 1, further characterized in that said central dividing wall runs lengthwise within header tank 12 . 4. A radiator 10 and integrated flow control valve according to claim 1, further characterized in that said tanks 12 and 14 are vertically oriented.
