A split-flow coolant system is provided. The split-flow coolant system may include a single inlet and multiple coolant distribution channels arranged inside a housing, or cooling plate, of the inverter. The coolant distribution channels may include a coolant chamber connected to the inlet and a coolant path running adjacent to various portions of the inverter. The coolant chamber splits into two separate coolant paths in the inverter housing, or cooling plate, that are then diverted to each of the motors. A first coolant path is diverted to the first motor where the coolant path is arranged to cool the first motor and a second coolant path is diverted to the second motor to cool the second motor. The separate coolant paths may connect to a common outlet at the end of the cooling path for the motors.
