GMC Sierra 3500 HD Radiator Support Assembly

The radiator support assembly is also often referred to as the radiator support panel or radiator core support. The primary purpose of the radiator support assembly is to provide a structural framework for mounting the radiator, cooling fans, and associated components. It helps maintain the proper position and alignment of the radiator, ensuring efficient cooling of the engine. It also serves as a protective barrier for the radiator and other front-end components, helping shield these critical parts from damage in the event of a front-end collision or an impact with road debris.
