Abstract: The present invention relates to a cooling circuit for a work machine that provides increased cooling capacity of a radiator without increasing the physical size of the radiator. The cooling circuit includes a jacket water pump, a jacket water portion of an engine and a radiator fluidly coupled to the circuit. A first powertrain oil cooler is fluidly coupled to the cooling circuit between the jacket water pump and the jacket water portion. A second powertrain oil cooler is fluidly coupled to the cooling circuit between the jacket water portion and the radiator. Positioning of the powertrain oil coolers in this manner increases the temperature differential between ambient air and coolant entering the radiator, therefore increasing cooling capacity of the radiator.
