A front grille, as opposed to side skirt and trunk grilles, is also known as a radiator grille. The name radiator grille is meant to signal its purpose of allowing cool air to flow inside the hood, cooling off many parts heated up by use and friction, but more specifically the vehicle's engine and radiator. The primary function of a grille is to allow your vehicle's engine to keep cool. As you drive, air is pulled through the grille which serves to provide ventilation through the engine bay. The way the grille is designed can have a considerable impact on its ability to cool the engine.
