The XDP Coolant Filtration System XD143 is designed to filter solid particles from your trucks coolant. Contaminants such as casting sand and sediment are known to damage many components in your cooling system. By removing these contaminants you are able to extend the life of your coolant, water pump, EGR cooler and other vital components. The XDP Coolant Filtration system does not require any modification to your factory hoses. Our pre-assembled, high-quality silicone hoses simplify the install and provided a clean finished look without using multiple ugly hose clamps. The included ball valves are extremely helpful for minimizing coolant loss during filter changes and also provide a shut-off to bypass the system should you ever need it. This system is built around an easy to find parts store filter and can be installed in no time with basic hand tools!
