An agricultural vehicle (10) includes an internal combustion engine (32), and a fluid cooling system (70) for cooling at least one component (32, 87) onboard the agricultural vehicle. The agricultural vehicle (10) is characterized in that: The fluid cooling system (70) is positioned in association with the internal combustion engine (32), and includes a housing (72, 102) and at least one cooling unit (74) arranged within the housing (72, 102). A door (108) is pivotally mounted relative to the housing (102). An actuator is connected with the door for moving the door between a closed position against the housing (102) and an open position allowing cleaning of an interior of the housing. An activator is coupled with the actuator, for selectively activating the actuator. A combustion air duct fluidly interconnects the interior of the fluid cooling system and the internal combustion engine, the combustion air duct including at least one baffle which is selectively operable to allow combustion air to enter the combustion air duct either from the interior or an exterior of the fluid cooling system
