Abstract
A method of controlling cooling fluid flow through a radiator system having multiple radiator cores comprises flowing cooling fluid through the radiator system, the radiator system comprising a first radiator core and a second radiator core, sensing a first temperature of ambient air, comparing the first temperature to a first threshold temperature and reducing flow through the first radiator core if the first temperature is below the first threshold temperature. The first radiator core has a first valve, and the second radiator core can have a second valve. The first valve can be opened to allow for parallel flow of cooling fluid through the first radiator core and the second radiator core between an inlet manifold and an outlet manifold and closed to interrupt flow of cooing fluid through the first radiator core between the inlet manifold and the outlet manifold.
