Mishimoto 17-19 Chevrolet/Gmc 6.6 L5p Duramax Performance Aluminum Radiator

GM designed the 6.6L L5P Duramax to meet the demands of its tough, dependable, and rugged customer base. However, the factory-installed plastic cooling components, particularly the radiator, fall short of those standards. Fortunately, the Mishimoto engineering team has stepped up with a robust radiator specifically designed for the 2017-2019 Chevrolet/GMC 6.6L L5P Duramax.

Our L5P aluminum radiator features a fully aluminum construction, meticulously crafted with stunning TIG welds for unparalleled strength and durability. This construction not only enhances the overall resilience of the radiator but also works in conjunction with our strategically designed core to provide superior heat dissipation. With a 25% increase in coolant capacity and a 14% increase in total core volume, our radiator significantly boosts your vehicle’s cooling performance, ensuring it can handle even the most demanding conditions.

The Mishimoto radiator is engineered to fit 2017-2019 L5P Duramax-equipped vehicles with only minor trimming of the radiator fan shroud needed to accommodate our thicker core. To further enhance your cooling system's longevity, we’ve included a Mishimoto Magnetic Drain Plug, which effectively captures metallic debris in your coolant, extending the life of all cooling components.

Like all of our Duramax products, this radiator is backed by the Mishimoto Lifetime Warranty, providing you with a lifetime of performance and peace of mind. Upgrade to the Mishimoto radiator today and ensure your Duramax remains as tough and reliable as you are!
