Fan horsepower requirements and the size of power train heat exchangers may be reduced in a vehicular cooling system that includes an inlet (14) for the receipt of ambient air and first and second heat exchangers (28), (40) in proximity to the inlet (14) to receive ambient air therefrom and which are respectively adapted to receive first and second heat exchanger fluids by the ambient air. The first and second heat exchangers (28), (40) are in side by side, substantially non superimposed relation to define first and second air flow paths (52, 54) extending in fluid flow parallel to a respective one of the heat exchangers (28), (40) from the inlet (14) to points (50), (52), (54) of discharge. A fan (44) flows air from the inlet (14) through the flow paths (52, 54) and a shutter (56) is located in one of the flow paths (54) and is movable between first and second positions respectively restricting air low and allowing relatively unrestricted air flow. An actuator (88) provided for moving the shutter (56) between the positions and a control (90, 98, 100) is provided for the actuator (88) which is responsive to power train and air conditioning system operating conditions.
