Abstract: A method is disclosed for operating a cooling system with a coolant pump for an internal combustion engine. The coolant pump is operated for a preset period of time after a starting of the internal combustion engine. The cooling system is switched over into a first warming-up operating mode, in which the coolant pump is not operated, in the case that a first warming-up condition is fulfilled.

Abstract: A system including startup, load, flow, and peak estimation modules. The startup module, during a startup period or in response to a startup of the engine, receives a temperature signal and generates a first condition signal. The load module determines a load on the engine and generates a second condition signal. The flow module, if the first condition signal indicates a temperature of the engine is less than a first predetermined temperature and if the second condition signal indicates the load is less than a predetermined threshold, operates a pump to circulate coolant during the startup period. The peak estimation module estimates a temperature of a hottest metal location on the engine. The flow module increases a speed of the pump if the temperature of the hottest metal location is greater than a second predetermined temperature or the load is greater than or equal to the predetermined threshold.

Abstract: The present disclosure relates to a method for determining an actuating value for a coolant pump or a control valve of a cooling system for an infernal combustion engine of a motor vehicle. In particular, a pre-control value for ascertaining the actuating value is determined in a first determination mode based on a prescribed first allocation as a function of an output variable of the infernal combustion engine and a temperature difference of a heat exchanger of the cooling system.
