ABSTRACT:
A coolant circuit contains an expansion tank to which at least one vent line is connected which is connected with an internal-combustion engine and/or a radiator. In order to shorten the warm-up phase of the internal-combustion engine, a stop valve is provided to block the connection of the vent line to the expansion tank during the warm-up phase. As a result, the coolant situated in the expansion tank is not circulated in the short circuit.
