Mishimoto has released a direct-fit performance aluminum radiator for the 2006–2010 Chevrolet/GMC 6.6L Duramax. Mishimoto performance radiators are manufactured from high-quality aircraft-grade aluminum with a 100% brazed aluminum core and polished end tanks. The Mishimoto 6.6L Duramax performance radiator offers increased cooling efficiency, and the all-aluminum TIG-welded construction provides a rugged design that can take the abuse of any environment or terrain. Pair your Mishimoto 6.6L Duramax aluminum radiator with our silicone coolant hose kit for the ultimate combination in cooling performance and reliability. The Mishimoto 6.6L Duramax aluminum radiator retains factory fitment and requires no modification to your truck. Whether you use your Duramax for tearing up the dragstrip or working at the job site, you can trust the Mishimoto performance radiator to keep your truck cool. As with all our Duramax performance parts, this aluminum radiator is protected by the Mishimoto lifetime warranty.
This radiator was designed to fit with the most updated lower hose from Chevrolet/GMC with a larger O-ring. 2006-2007 model-year owners will need to purchase the Mishimoto radiator hose kit or the 2008-2010 OEM lower hose (part #25841843) from Chevrolet/GMC.
