A work vehicle (10) is disclosed that includes an engine (26) and a hood enclosure (12) at least partially surrounding the engine (26). The hood enclosure (12) may include a front grille (38) and a secondary grille (40) spaced apart from the front grille (38). The hood enclosure (12) may also at least partially define an airflow compartment (44). In addition, the work vehicle (10) may include a heat exchanger (48) disposed in the airflow compartment (44) between the front grille (38) and the engine (26) and at least one cooling fan (50, 52, 150, 182) disposed in the airflow compartment (44) between the heat exchanger (48) and the engine (26). The at least one cooling fan (50, 52, 150, 182) may generally be configured to generate a reversible airflow within the airflow compartment (44) between the front grille (38) and the secondary grille (40). |
