Abstract
Apparatus for cooling an internal combustion engine of a motor vehicle is provided having a thermostatic valve for controlling the coolant flow and having at least one fan associated with the radiator. The fan (or fans) can be operated in several output stages and the thermostatic valve can be adjusted to at least two different opening temperatures. When the thermostatic valve is adjusted to a higher opening temperature, operation of the fan in the output stage associated with a lower coolant temperature is blocked.
