Abstract
A work vehicle, such as a compact loader, has a cooling system including a cooling fan generating air flow to cool engine components. The fan is shown as an axial flow fan having an inlet throat in a shroud surrounding the fan. The inlet throat is under a negative or low pressure, and a duct or conduit is connected to the inlet throat and to a precleaner of an air filter assembly providing combustion air to the engine. The negative pressure in the inlet throat causes air to flow from the precleaner to the inlet throat.
