The radiator support in your vehicle keeps the entire front end together. It is where the radiator, fan, and AC components are mounted. Apart from that, it also gives mounting points to the front of the car for the bumper cover, fenders, and headlights.
If your support has been damaged in an accident, the only solution is replacement. To get a quality look to the front end, a new radiator support is required to give the proper look and fitment of all the body components.
