Over time, your factory radiator loses its ability to properly cool your engine.

Damage, dirt, debris, and bugs will clog the core of the radiator, not allowing air to pass over the fins to properly cool down the coolant, meaning temperatures will continue to rise, especially noticeable on hot days when you're hauling.

Bring new life to your Cummins by swapping in this fresh radiator from CSF.
