摘要： The present disclosure relates to a cooling system (100) for an internal combustion engine (14). The cooling system (100) comprises a high-temperature cooling circuit piping (44, 46, 48) including high-temperature cooling circuit connection ports (49) and a low-temperature cooling circuit piping (64, 66) including low-temperature cooling circuit connection ports (67). The cooling system (100) further comprises a two-stage charge air cooler unit (50; 504, 506) including a first cooling stage (42) with first cooling stage connection ports (43) and a second cooling stage (60) with second cooling stage connection ports (61). The first cooling stage (42) provides a first heat transfer performance and the second cooling stage (60) provides a second heat transfer performance different from the first heat transfer performance. The two-stage charge air cooler unit (50) includes a first mounting position and a second mounting position. In the first mounting position the first cooling stage (50) is connected to the high-temperature cooling circuit connection ports (49) via the first cooling stage connection ports (43) and the second cooling stage (60) is connected to the low-temperature cooling circuit connection ports (67) via the second cooling stage connection ports (61). In the second mounting position the first cooling stage (42) is connected to the low-temperature cooling circuit connection ports (67) via the first cooling stage connection ports (43), and the second cooling stage (60) is connected to the high-temperature cooling circuit connection ports (49) via the second cooling stage connection ports (61).
