Beschreibung
Zusammenfassung:	The invention relates to a cooling circuit (10) for an internal combustion engine (12) provided with an exhaust gas recirculation circuit, comprising at least one first, cooling loop (14) associated with the engine (12), a second, heating loop (30) comprising at least one unit heater (34), and a third loop (40) for cooling the exhaust gases, which comprises at least one heat exchanger (42) for cooling the exhaust gases of said recirculation circuit, characterised in that said third loop (40) for cooling the exhaust gases comprises at least one pump (44), heating means (46) for selectively heating the cooling liquid circulating in said third loop (40), and control means (48) which are selectively controlled for isolating the third loop (40) from the rest of the cooling circuit (10). The invention also relates to a method for controlling such a cooling circuit (10).
