ABSTRACT:
In a cooling system for a motor vehicle engine having indirect charge air cooling, including a general cooling circuit for cooling a power-generating unit which comprises a coolant pump and a main coolant cooler, and an additional cooling circuit which branches off at an output point from the general cooling circuit and returns to the latter at an in-coupling point between the main coolant cooler and the coolant pump and contains an additional coolant cooler, means are provided for sensing the coolant temperature in an area where the coolant of the general cooling circuit and of the additional cooling circuit are mixed and also means for controlling the coolant flow as a function of the sensed coolant temperature.
