Keep the cooling system in your 2007.5-2018 Dodge 6.7L Cummins working properly with a new radiator. Brands including XDP X-TRA Cool, Mishimoto, CSF, AFE, and Flex-A-Lite manufacture high-quality Radiators to replace the failed component on your vehicle. A radiator is a type of heat exchanger that has hot coolant flowing through it, the outside air passes over the radiator fins and allows heat to dissipate. Shop today at XDP and ensure that your radiator is up to the task and can handle the heat! Over time your stock radiator will need to be replaced either due to leaking, becoming clogged up, or the plastic inlets and outlets can break from constant clamp pressure.
