To realize an efficient ventilation of the cooling liquid for an electric motor for a motor vehicle.SOLUTION: A cooling system for an electric motor for a motor vehicle includes: a looped conduit system 4 for conducting a first cooling liquid 5 to be circulated; a circulation pump 6 for conveying the first cooling liquid 5 in the looped conduit system 4 in a first circulation direction 7; an expansion tank 8 filled at least partially with the first cooling liquid 5 to be circulated in the looped conduit system 4 and at least partially with a gas 9; a motor input terminal 10 for fluidically connecting the looped conduit system 4 on an input side to an electric motor 2 to be temperature-controlled; a motor output terminal 11 for fluidically connecting the looped conduit system 4 on an output side to the electric motor to be temperature-controlled; and a first heat exchanger 12 for dissipating heat from and/or supplying heat to the first cooling liquid 5 to be circulated in the looped conduit system 4. The expansion tank 8 is configured with an aperture 13 that is open toward an ambient environment 14.SELECTED DRAWING: Figure 1
