Swap out the leaking radiator in your 2020-2022 Ram 1500 3.0L EcoDiesel with a new durable replacement. Shop today at XDP and ensure that your radiator is up to the task and can handle the heat! Find high-quality replacement Radiators from brands such as XDP X-TRA Cool, Mishimoto, CSF, AFE, and Flex-A-Lite. 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. 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.
