ABSTRACT:
In a cooling circuit for an internal combustion engine of a motor vehicle including a pump device arranged upstream of the internal combustion engine, a cooler having an inlet side connected to a coolant outlet of the internal combustion engine and an outlet connected via a coolant line to the inlet side of the pump device, a cooler bypass line extending from the outlet side of the internal combustion engine to the inlet side of the pump device while bypassing the cooler and a switching valve arranged in the coolant line between the cooler and the pump device, a switching valve bypass duct is provided bypassing the switching valve and including a valve device which is open when the engine is shut down for reliable ventilation of the second coolant line during filling of the cooling circuit.
