Abstract
Abstract A cooling system for a work vehicle (e.g., a wheel loader) having reduced air restriction noise includes a cooling system frame defining an enclosure therein. A cooler (e.g., an engine cooler) and a fan are coupled to the cooling system frame, the fan imparting a velocity on a flow of cooling air flowing through the cooler. An air deflection member is coupled to the cooling system frame and extends into the enclosure to shape the flow of cooling air as it travels between the cooler and the fan. The air deflection member defines a fluid reservoir (e.g., a hydraulic reservoir) for holding a fluid (e.g., a hydraulic fluid).
