1. A cooling system for a vehicle, comprising:
a cooling circuit through which a coolant is flowable;
the cooling circuit including:
a first heat source coolable at a lower temperature level;
a first radiator;
a second heat source coolable at a higher temperature level; and
a second radiator;
wherein, in the cooling circuit, the first heat source, the first radiator, the second heat source, and the second radiator are connected in series with one another;
wherein the cooling circuit further includes a hydraulic switch dividing the cooling circuit into (i) a first partial circuit with the first heat source and the first radiator and (ii) a second partial circuit with the second heat source and the second radiator;
wherein the first partial circuit includes:
a warming-up bypass line connected in parallel with the first heat source and through which the coolant is flowable to bypass the first heat source; and
a warming-up bypass valve via which the warming-up bypass line is openable and closable.
