ABSTRACT:
A cooling system for an internal combustion engine mounted in a vehicle includes a first flow circuit with a pump for circulating coolant via ducts in the cylinder block of the engine and a radiator. The first flow circuit is separated from atmospheric pressure. The cooling system also includes a second flow circuit which is provided with a coolant reservoir with a normal pressure which is lower than the pressure in the first flow circuit, and a pump for circulating coolant via a pipeline between units with a cooling requirement and a second radiator. The second flow circuit is connected to the first flow circuit via a one-way valve opening in the direction of the first flow circuit.
