摘要:
The invention relates to a method for operating a fluid circuit (1) of a motor vehicle, which fluid circuit has a main circuit (2), a secondary circuit (3) connected to the main circuit (2) by means of a mechanical thermostatic valve (9), and an electric fluid-conveying device (4) for conveying a fluid. According to the invention the fluid-conveying device (4) is set to a certain test rotational speed in a test operating mode and the actual amperage of the current required by the fluid-conveying device (4) is determined during a testing time period, wherein the actual amperage is stored as a first amperage value in the case of an actual temperature of the fluid that is less than a switching temperature of the thermostatic valve (9) and is stored as a second amperage value in the case of an actual temperature that is greater than the switching temperature, wherein proper function of the thermostatic valve (9) is granted if the second amperage value is greater than the first amperage value. The invention further relates to a fluid circuit (1) for a motor vehicle.
