Abstract
In the case of a cooling system for an internal-combustion engine of a motor vehicle comprising a radiator and a thermostatic valve by means of which the temperature of the coolant can be controlled in a warm-up operation, a mixed operation and a radiator operation. The thermostatic valve containing an expansion element can be electrically heated for reducing the coolant temperature, the expansion element being designed such that the coolant temperature is controlled without any heating of the expansion element in the warm-up operation and/or the mixed operation to an upper operating limit temperature. In addition, a temperature switch is provided which, as a function of the coolant temperature detected at the or near the radiator outlet, releases the heating of the expansion element as required in order to shift the method of operation of the cooling system toward the radiator operation.
