Abstract

The invention relates to a cooling strategy for an internal combustion engine (1) which has at least one cylinder head (2) and an associated cylinder block (3). A coolant flows in a coolant circuit (4), with at least one control element (6, 7, 8, 9) being assigned to the coolant circuit (4). During a warmup of the internal combustion engine, in successive phases, the coolant flow is conducted to separate cooling regions by the control elements (6, 7, 8, 9), wherein in an operating mode at operating temperature which follows the warmup, the coolant flow is conducted to separate cooling regions by the control elements (6, 7, 8, 9) taking into consideration the operating states of the internal combustion engine.
