Abstract
A process for monitoring the coolant level in a cooling system, in particular in a motor vehicle in which the relative pressure and the temperature of the coolant are measured on the high-pressure side of the coolant circuit, using the measured pressure value. A temperature assigned to the pressure value is established on the basis of a coolant specific function (temperature=f (pressure)) and the undercooling of the coolant is then determined by subtracting the measured temperature from the assigned temperature, which undercooling is analyzed as a measure for the coolant level.
