Radiator Grille
- shares

The grating that admits cooling air to car's radiator. The radiator grille is the part of the body shell on the front of your car that covers the area where the air enters. The radiator grille can also be part of the bumper on some cars (although not very common). The radiator is connected to the shroud for the radiator, which directs the air that comes in through the radiator grille to the radiator only. This prevents the air from escaping around the radiator and failing to cool the engine. On newer cars, the radiator grille has been lowered to take advantage of lower hood lines, brought about by an effort to increase fuel efficiency. Radiator grilles are very important as they help keep your engine cool. It is important to make sure yours is not covered with dust, leaves or other objects that might prevent good air flow.
