Abstract

A method and a system for cooling an internal combustion engine having charge air feed, which has a first and a second cooling loop, of which the first cooling loop is operated at a higher temperature level than the second cooling loop, and in which the charge air feed has at least one intercooling unit which is thermally coupled to the second cooling loop, having a controllable coolant throughput. The system includes at least one shutdown element in the second cooling loop for throttling the coolant throughput in the second cooling loop to 0 (zero). Coolant throughput may be shut down during the operation of the internal combustion engine as a function of an operating parameter of a vehicle component.
