ABSTRACT:
In the method of monitoring a cooling fluid circuit of an internal combustion engine with setting a first error signal if a deviation of an actual value of a temperature from a desired value of the temperature exceeds a predetermined amount, a second error signal is set, which indicates a possible lack of antifreeze if a starting temperature is below the freezing point of water, a first error signal was present, the first error signal is no longer present after a predetermined time which is a function of the engine starting temperature and a build-in energy balance exceeds a threshold which is a function of the engine starting temperature.
