1. A radiator system for cooling an internal combustion engine, the radiator system comprising:
a first radiator core having a first inlet and a first outlet;
a second radiator core having a second inlet and a second outlet;
an inlet manifold connected to the first inlet and the second inlet;
an outlet manifold connected to the first outlet and the second outlet;
a cooling fluid circuit configured to circulate a cooling fluid through the inlet manifold, the first radiator core, the second radiator core, the outlet manifold, and the internal combustion engine;
a first valve positioned on the inlet manifold to control a flow of the cooling fluid through the first radiator core;
an ambient air temperature sensor configured to sense a temperature of ambient air;
a cooling fluid temperature sensor configured to sense a temperature of the cooling fluid within the cooling fluid circuit;
a fan configured to drive the ambient air across the first radiator core and the second radiator core;
a fan speed sensor configured to sense a rotational speed of the fan; and
a memory device having stored therein instructions for, based on an output of at least one of the ambient air temperature sensor, the cooling fluid temperature sensor, and the fan speed sensor,
opening the first valve to allow for parallel flow of the cooling fluid through the first radiator core and the second radiator core between the inlet manifold and the outlet manifold; and
closing the first valve to interrupt the flow of the cooling fluid through the first radiator core between the inlet manifold and the outlet manifold.
