Abstract: A water management system for venting hot air out of the engine compartment of a vehicle through the hood of the vehicle includes a louver cover positioned over vent holes in the hood. A gasket is sandwiched between the louver cover and the hood. A water tray is positioned under the hood and is bolted to the louver cover. The water tray includes an open edge that is juxtaposed with a trough in the fender of the vehicle and a barrier wall opposite the open edge. The barrier wall is slightly vertically distanced from the hood, such that hot air from the engine compartment can flow over the barrier wall and out of the vent holes, but water seeping into the vent holes is blocked by the barrier wall from entering the engine compartment, and must instead flow into the fender trough.
