Abstract
A shroud assembly for an engine cooling fan positioned between an engine and a radiator includes a ring shroud, a radiator shroud, and a flexible boot. The ring shroud is mounted adjacent to the fan and includes a locking feature. The radiator shroud, which is mounted to the rear of the radiator, has a first end with a first aperture for receiving air flowing rearwardly through the radiator, and a second end with a second aperture for discharging air received by the first aperture. A first end of the flexible boot engages the locking feature of the ring shroud to secure the flexible boot to the ring shroud. A second end of the flexible boot contacts the radiator shroud so that the boot provides fluid communication between the ring shroud and the radiator shroud.
