An arrangement for a supercharged combustion engine (2), including at least one compressor (6a, 6b) for compressing air in a first cooling system, the first cooling system having a first circulating coolant, a second cooling system with a second circulating coolant which during normal operation of the combustion engine is at a lower temperature than the first coolant in the first cooling system, at least one charge air cooler (9a, 9c) applied in the air inlet line (8) and being cooled by coolant from the second cooling system. The second cooling system includes a first radiator element (24) and a second radiator element (36) arranged in series with the first radiator element (24) in the second cooling system, so that at least part of the coolant which circulates in the second cooling system undergoes two steps of temperature lowering during a single round of circulation in the second cooling system. |
