Abstract: A fan shroud is provided having upper and lower sections. The sections are designed to mateably engage one another at mating flanges so as to form an air passage between a fan and a cooling module of the vehicle. The upper section of shroud includes an aspirator portal in an upper surface thereof. An aspirator is provided having an air intake and an air outlet. The aspirator is supported in the lower section of the shroud proximal to the fan with the air outlet facing the fan. An engine intake air pre-cleaner unit having an air intake, an aspirator port, and an air exhaust is mounted to the shroud by aligning mounting tabs on the pre-cleaner with mounting bosses on the shroud so that the aspirator port is disposed in proximity to the aspirator portal in the upper section of shroud. One end of an aspirator hose is connected to the aspirator port of the pre-cleaner and passes through the aspirator portal. The other end of the aspirator hose is connected to the air intake of the aspirator.

Abstract: A fan shroud having an integrated aspirator is provided comprising an upper section and a lower section. The upper section and lower section are designed to mateably engage one another so as to form an air passage between a fan and a cooling module of a vehicle. The upper section of the shroud includes an air duct formed by a channel in the shroud and a similar channel in a duct cover so that when the duct cover is mated to the upper section of the shroud a passage is created. A first end of the passage terminates at an aperture disposed in an end of shroud situated proximal to the fan. A second end of the passage curves upwardly to a nozzle provided on the top side of the duct cover. A pre-cleaner unit having an air intake and an air exhaust is aspirated through an aspirator port. When the pre-cleaner is mounted to the shroud, the aspirator port is disposed in the nozzle of the duct cover. The aspirator port is thus in communication with the air duct and the shroud aperture.
