ABSTRACT:
A cooling system for an internal combustion engine of a motor vehicle having an electrically heatable thermostatic valve that contains a coolant bypass valve. Below the opening temperature, the coolant bypass valve limits a flow cross section for the coolant quantity flowing through the coolant bypass to a minimal cross section which is enlarged when the opening temperature is exceeded. When a preselected temperature is reached during the warm-up operation, a control element switches on the heating element for a predetermined time period.
