Abstract
The invention relates to a coolant circuit (5, 6, 7, 7a, 8, 8a), preferably for cooling a drive or an engine (2) of a motor vehicle (1), in particular of a passenger car, comprising: a controller (8) which, in order to control the temperature of a cooling fluid (7a), activates an electrically operated fan motor (5). The controller (8) is in thermal contact with the cooling fluid (7a) in order to be cooled and is formed to detect the temperature of the cooling fluid (7a) by way of a temperature sensor (8a) which is preferably provided at the controller (8). A defined temperature of the cooling fluid (7a) can thereby be set without a control signal from a master control or regulating device being required for this purpose.
