Abstract
A venting arrangement for a cooling circuit of an internal combustion engine, having a vent line which connects a radiator to a top section of an expansion tank located at a higher level with regard to the top of the radiator. In order to avoid trapping of air inside the vent line, a vent valve in the form of a flap or diaphragm valve is installed at the highest point of the vent line, via which vent valve the trapped air can escape during travelling operation and during filling. By the arrangement of the vent valve inside the expansion tank, the cooling water expanding during running of the engine and discharging via the vent valve remains in the expansion tank.
