Swap out the leaking radiator in your 1999-2003 Ford 7.3L Powerstroke with a new durable replacement. 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. Get the high-quality replacement Radiator your vehicle needs from manufacturers including XDP X-TRA Cool, Mishimoto, CSF, AFE, and Flex-A-Lite. 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.
