Kühlsystemventil, das ein bewegbares Element umfasst, das selektiv zwischen einer geöffneten und einer geschlossenen Stellung zum Gestatten oder Beschränken eines Kühlmittelstroms durch das Ventil bewegbar ist, wobei das bewegbare Element Folgendes umfasst:einen schmelzbaren Abschnitt, der dazu konfiguriert ist, dahingehend zu schmelzen, einen Kühlmittelstrom durch das bewegbare Element zu gestatten, wenn der schmelzbare Abschnitt eine Schwellentemperatur erreicht; undein Heizelement, das dahingehend steuerbar ist, den schmelzbaren Abschnitt zu erhitzen. Methods and systems are provided for a cooling system valve comprising a fusible insert and a heating element coupled to the insert. In one example, in response to an increase in coolant temperature to above a first threshold temperature, a movable element of the cooling system valve may be actuated to a fully open position and in response to an increase in coolant temperature to above a second threshold temperature with the movable element in a fully open position, electric current may be routed through the heating element to heat and melt the fusible insert. By melting the fusible portion, coolant may flow through an opening created in the movable element.
