A method and a device for rapidly warming up a liquid-cooled internal combustion engine, in particular of a motor vehicle engine, by warming up the cooling liquid. The cooling liquid is warmed in a simple manner without additional provision of heating elements in that the cooling liquid is warmed using a generator that is operated during a heating phase at an operating point having high power loss and at the operating temperature of the engine at an operating point having low power loss.
