Systems and methods for water management in a vehicle using a fluid management assembly are disclosed. The fluid management assembly includes a housing in fluid communication at one end with a vent in the hood of the vehicle and at a second end with a radiator of the vehicle. Air flow from the radiator is directed to the vent, and water and other liquids entering the vent are diverted away from the radiator via a drainage spout extending from a bottom side of the fluid duct assembly.
