The 2011-2016 Chevrolet 6.6L Duramax LML radiator offers a seamless direct replacement for your factory unit. Designed for perfect fitment, it requires no bending, cutting, or additional modifications during installation. Constructed with OEM-grade plastic end tanks paired with an aluminum core, this radiator delivers reliable, stock-level cooling performance. Over time, stock radiators are prone to developing leaks, clogs, or cracks from plastic components under constant pressure. This 2011-2016 Chevrolet 6.6L Duramax LML radiator provides an ideal solution to restore your cooling system's efficiency. As always, it comes backed by the Mishimoto Lifetime Warranty.
