Abstract
A method of cooling coolant in a coolant circuit of an internal combustion engine of a motor vehicle includes: evaluating parameters of the internal combustion engine and the motor vehicle with a thermostatic valve control device; based on the evaluation of the parameters, controlling with the thermostatic valve control device adjustment of a thermostatic valve for controlling coolant flow from a radiator and coolant flow from a bypass line around the radiator into a combined coolant flow to the internal combustion engine; communicating a signal based on the evaluation of the parameters from the thermostatic valve control device to a fan control device which controls operation of a fan that cools coolant in the radiator to a target temperature; and setting the target temperature of the fan control device through the communication. Subsequently, the fan control device controls the cooling by the fan as a function of the target temperature set by the signal received from the thermostatic valve control device.
