  "textContent": "A cooling system for an electric traction machine for a motor vehicle includes a circuit system for conducting a first coolant to be circulated, a circulation pump for conveying the first coolant in the circuit system in a first circulation direction, and an expansion tank filled at least partially with the first coolant and at least partially with a gas. The cooling system also includes a motor input terminal for fluidically connecting the circuit system on an input side to the electric traction machine, a motor output terminal for fluidically connecting the circuit system on an output side to the electric traction machine, and a first heat exchanger for dissipating heat from and/or supplying heat to the first coolant. The expansion tank is exclusively connected on a gas side to at least one volume equalization tank which is closed gas-tight to an environment.",
