Swap out the leaking radiator in your 2011-2016 Chevy/GMC 6.6L LML Duramax with a new durable replacement. Shop today at XDP and ensure that your radiator is up to the task and can handle the heat! A radiator functions as a heat exchanger and as hot coolant flows through the core, outside air passes through the radiator fins helping to dissipate heat. Over time your factory radiator can require replacement due to leaks, clogs, front-end collisions, and many other reasons. 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.
