Abstract: Equipping engine cooling fans with flaps, in particular ram-air flaps, which are opened by the relative wind and can close again by means of gravity at a vehicle standstill, is known. Until know, it has been common to install such ram-air flaps manually on a frame of the engine cooling fan. However, all of said embodiment concepts require complex motion guidance during the installation in/on the frame.
