Abstract
The present invention relates to a cooling system for an internal combustion engine with an electrically driven coolant pump designed to circulate a coolant through the internal combustion engine and through a radiator designed to dissipate the heat, wherein a safety device is provided which has a device for recognizing cases of emergency and an emergency operating device, wherein the device for recognizing cases of emergency is devised to detect a perturbation in the area of the electrically driven coolant pump. Increased reliability is achieved by devising the emergency operating device in such a manner that, in case of a perturbation in the area of the coolant pump, it causes a mechanical connection of the coolant pump with a component part driven by the internal combustion engine to be established.
