Abstract
A fan for a cooling system of a motor vehicle has a radial impeller with multiple vanes which are arranged between an impeller bottom and a cover disk. A stationary intake nozzle extends axially into a cover disk intake, forming an annular gap between the cover disk intake and the intake nozzle. The impeller bottom, the vanes and the cover disk of the radial impeller are made in one piece of a plastic material. A separate air guide ring is arranged on the cover disk at the cover disk intake.
