Abstract
A method of regulating the temperature of the coolant circuit in an internal combustion engine is described, using an electrically operated coolant pump whose speed regulates or controls the cooling capacity. A great excess of heat can be dissipated and rapid heating of the internal combustion engine can be achieved by using an additional bypass line having corresponding thermostatic valves.
