Shopping for Radiator Support

Radiator Support Shopping Info

How Much Does a Radiator Support Replacement Cost?

A replacement radiator support could cost you anywhere between $50 and $250 on parts alone. An auto repair shop may charge you $90 to $200 for labor, but the rates may vary depending on your area.

What Is a Radiator Support?

A radiator support is a steel, plastic, or aluminum frame that holds the radiator and the radiator cover in place. It also attaches your radiator to the side aprons and the upper and lower rails of your engine assembly frame. By locking your radiator in place, the radiator core support helps keep the rest of your interior parts aligned with your fenders and hood.
