High-Capacity Aluminum Radiator for 2011-2016 Chevy Silverado 6.6L Duramax Diesel
The Mishimoto MISR13244 is a direct-fit aluminum radiator engineered for the 2011-2016 Chevrolet Silverado HD equipped with the 6.6-liter Duramax diesel engine. The MISR13244 features an aluminum core with significantly greater coolant capacity and thermal transfer efficiency than the factory plastic-tank radiator, reducing engine coolant temperatures during towing, hauling, and high-load operation. The MISR13244 uses all OEM mounting points and upper/lower hose connections for a direct-fit installation with no modifications required. It includes a lifetime warranty from Mishimoto and is the preferred replacement radiator for Silverado owners experiencing coolant temperature concerns or replacing a failed factory unit.

FAQ
What is the MISR13244?The MISR13244 is the Mishimoto direct-fit performance aluminum radiator for the 2011-2016 Chevrolet Silverado HD with the 6.6L Duramax diesel, engineered to reduce coolant temperatures and replace the factory plastic-tank radiator with a full aluminum unit backed by the Mishimoto Lifetime Warranty.
What Duramax engine does MISR13244 fit?The MISR13244 fits the 6.6L Duramax diesel as installed in the 2011-2016 Chevrolet Silverado HD. This covers the LML and LGH engine variants used in the 2500 and 3500 HD truck lines during this production window.
Does MISR13244 require any modifications to install?No. The MISR13244 is a direct-fit radiator that uses all OEM mounting points and upper/lower hose connections. Standard installation requires no cutting, drilling, or fabrication on a stock 2011-2016 Silverado Duramax.
Why upgrade from the factory radiator to MISR13244?The factory plastic-tank radiator on the 2011-2016 Silverado Duramax is prone to plastic tank degradation and end-tank cracking over time. The MISR13244's all-aluminum construction eliminates this failure point and improves coolant capacity and heat rejection for towing and high-load operation.
Does MISR13244 fit the GMC Sierra Duramax as well?The MISR13244 is listed specifically for the Chevrolet Silverado application. The GMC Sierra HD shares the same platform and engine, so cross-compatibility is likely, but verify fitment against the Mishimoto application guide before ordering for a Sierra.
What warranty does MISR13244 carry?Mishimoto backs the MISR13244 with its Lifetime Warranty covering defects in material and workmanship for as long as the original purchaser owns the vehicle.
Can MISR13244 handle towing loads?Yes. The MISR13244 is specifically designed for the increased thermal demands of Duramax diesel towing and hauling applications. Its aluminum core and higher coolant capacity are intended to maintain lower operating temperatures compared to the factory radiator during sustained high-load operation.
Is MISR13244 compatible with factory transmission cooler lines?The MISR13244 is engineered to OEM dimensions and connection points. Factory transmission cooler line routing should be compatible, but verify your specific transmission cooler routing before installation.
