Keep the cooling system in your 2017-2019 Chevy/GMC 6.6L L5P Duramax working properly with a new radiator. 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. A radiator serves as a type of heat exchanger and as hot coolant flows through it, the outside air passes over the radiator fins allowing heat to dissipate. Shop now at XDP and make sure your cooling system and radiator can handle the heat! 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.
