ABSTRACT:
A cooling arrangement for a liquid-cooled internal-combustion engine of a motor vehicle has a temperature-controlled thermostatic valve, through which the coolant is completely or partially either guided through the radiator or, through a short-circuit pipe between the forward flow and return flow pipe, is guided past the radiator, with the distance covered by the motor vehicle after the vehicle start being compared with a limit distance. This limit distance is determined such that, when the limit distance is covered in the normal driving operation, the coolant temperature in the coolant circuit of the internal-combustion engine remains well under the opening temperature of the thermostatic valve which is not acted upon by current and therefore under the boiling temperature. The thermostatic valve is acted upon by current from the vehicle start as long as the distance covered after the vehicle start is shorter than the limit distance.
