The invention concerns a method for regulating the temperature of an engine, in particular an internal combustion engine 12, in the case of which the engine is interconnected with a radiator 16 via at least one forward-delivery line 35 and at least one return-delivery line 44 within a cooling circuit 14, which said radiator can be bypassed via a valve-controlled bypass line 48 between the at least one forward-delivery line 35 and the at least one return-delivery line 44. Additionally, the cooling circuit 14 comprises at least one pump capable of being controlled via open-loop and/or closed-loop control, in particular an electric pump 34 for pumping a coolant through the connecting lines 32 of the cooling circuit 14, as well as an electronic control unit 52 that controls the cooling capacity of the cooling circuit 14 via open-loop and/or closed-loop control. It is proposed, according to the invention, that at least one component temperature of the engine 12 be determined based on the coolant temperature and the volumetric flow of the coolant through the engine 12.
