Abstract
The disclosure relates to a method for operating a drive device of a motor vehicle, wherein the drive device has at least one heat-generating device and a cooling circuit for cooling the heat-generating device, and at least one first coolant cooler of the cooling circuit and at least one second coolant cooler of the cooling circuit are fluidically connected to the heat-generating device. It is thereby provided that the first coolant cooler and the second coolant cooler are fluidically connected in parallel to the heat-generating device, and that coolant arriving from the heat-generating device be divided by means of a control mechanism between the first coolant cooler and the second coolant cooler. The disclosure furthermore relates to a drive device of a motor vehicle.
