Swap out the leaking radiator in your 2004.5-2007 Dodge 5.9L Diesel with a new durable replacement. Over time your factory radiator can require replacement due to leaks, clogs, front-end collisions, and many other reasons. 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. 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. Shop today at XDP and ensure that your radiator is up to the task and can handle the heat!
