Abstract (en)
[origin: DE19939138A1] The invention relates to a method for regulating the temperature of the coolant circuit of an internal combustion engine using an electrically operated coolant pump. According to said method, the speed of said pump regulates or controls the cooling capacity. An additional bypass line with appropriate thermostat valves ensures that considerable excesses of heat can be dissipated and that the combustion engine can be rapidly heated.
