Mishimoto 17-19 Chevrolet/GMC 6.6 L5p Duramax Radiator

The factory radiator in your 2017-2019 Chevrolet or GMC truck with the 6.6L L5P Duramax engine is built for everyday use, but it might not keep up when you're pushing your truck hard. Mishimoto has developed a robust, all-aluminum radiator designed to handle the demands of your Duramax. This radiator replaces the stock plastic unit with a much stronger, all-metal construction that's professionally fabricated with TIG welds, ensuring it can withstand tougher conditions.

This Mishimoto radiator offers a significant upgrade in cooling performance. Its core design provides a 25-percent increase in coolant capacity and a 14-percent increase in total core volume compared to the stock radiator. This means more coolant can circulate and dissipate heat more effectively, helping to keep your engine temperatures in check, especially under heavy loads or in demanding situations. The radiator is designed to fit 2017-2019 L5P Duramax equipped trucks, though you may need to trim the fan shroud slightly to accommodate the thicker core. To further protect your cooling system, it includes a Mishimoto magnetic drain plug that helps capture any metallic debris circulating in your coolant.

This radiator is a solid option for anyone looking to improve the cooling system's reliability and performance on their Duramax truck. It's backed by the Mishimoto Lifetime Warranty, giving you peace of mind for a lifetime of performance.
