1. A method comprising:
pumping, using a pump of a cooling system, coolant into a main coolant line connecting an outlet of the pump to a generator while the generator is generating electrical power;
connecting an external circuit bypass valve in an external circuit bypass line in fluid communication between the main coolant line and a source of the coolant;
receiving an input through an input port of a control unit from at least one of the cooling system or the generator; and
based on the input, regulating a flow of the coolant into the cooling system using a pressure relief valve to recirculate a portion of the coolant back to an inlet of the pump, wherein using the pressure relief valve includes actuating the pressure relief valve based on the input from at least one of the cooling system or the generator.
