An inlet air passage in the aerodynamically configured front end of a motor vehicle directs an inlet air stream at an inclination upwardly from the bottom of the front end of the vehicle and across a radiator for cooling engine coolant and wherein the radiator has coolant tubes and air centers for forming air flow passages through the radiator between spaced headers. The tubes are inclined with respect to the vertical headers at an angle selected to locate the air flow passages parallel to an inlet air stream for aligning the inlet air stream with the air flow passages for reducing air pressure drop across the radiator.
