Radiator Parts & Assemblies

The part that holds a radiator in place is called a radiator support or radiator mounting bracket. In heavy-duty trucks and equipment, this may also include side rails, crossmembers, bolt straps, and washer bars that secure the radiator assembly within the vehicle frame and ensure proper alignment with the cooling fan and shroud.

A radiator core refers to the central heat-exchange section made up of tubes and fins, excluding tanks and side rails. A complete radiator assembly includes the core plus top and bottom tanks, side rails, fittings, and mounting hardware. Cores are used for re-coring repairs, while complete assemblies are used for direct drop-in replacement.
