1. A vehicle cooling system comprising:

  • a closed loop coolant flowpath connecting an electrically driven coolant pump and a radiator, the electrically driven coolant pump operable to circulate coolant through the closed loop coolant flowpath through the radiator, the closed loop coolant flowpath further being in flow communication with a plurality of non-engine components of the vehicle to receive coolant circulated by the electrically driven coolant pump and provide the coolant to the radiator;

    an electrically driven radiator fan operable to push air across the radiator; and

    a controller configured to control the electrically driven coolant pump and the electrically driven radiator fan to operate independently of an operating condition of an engine of the vehicle in response to a temperature condition of at least one of the plurality of non-engine components, wherein the controller is further operable to increase a speed of at least one of the electrically driven coolant pump and the electrically driven radiator fan in response to a demand for increased coolant flow in the closed loop coolant flowpath.
