Your GM Duramax truck (2001-2007 and 2011-2019 models) deserves the best in thermal management to protect its long-term health and performance. The Banks Power 13252 Oil Cooler Upgrade Kit is an essential investment engineered to significantly lower oil temperatures and substantially extend the life of your engine oil compared to the restrictive factory unit. Utilizing a superior 19-plate design, this upgrade vastly increases cooling stack surface area and the sheer number of cooling plates, directly resulting in better heat rejection. For a stock truck operating at 450 horsepower, the Banks cooler already offers a 22% improvement in heat dissipation over the 14-plate factory oil coolers found in 2017-2019 models. This performance gap widens dramatically on modified, high-output engines; a 600-horsepower truck operating under a higher RPM and load will experience up to 31% more heat rejection, a critical factor in maintaining oil integrity and preventing premature engine wear. The difference is even more profound when upgrading from the older 10-plate (2001-2007) and 11-plate (2011-2016) coolers, underscoring the necessity of this upgrade for any Duramax owner seeking peak efficiency and reliability. The enhanced oil flow and increased surface area ensure the cooler sheds more BTUs of heat while diligently maintaining proper oil pressure.

Installing the Banks 13252 Oil Cooler Upgrade Kit is a proactive step in preserving the heart of your Duramax. Excessive heat is the enemy of engine oil; it accelerates breakdown, reduces viscosity, and ultimately compromises the vital protection your engine needs. By efficiently shedding maximum BTUs of heat, the Banks cooler ensures your oil stays within its optimal operating range, extending oil life and mitigating the risk of thermal-related damage, which is especially crucial for trucks used for towing, hauling, or high-performance driving. This kit provides superior, measurable thermal regulation through its thoughtfully engineered design, delivering not just a part, but a foundational reliability upgrade that safeguards your investment, maximizes engine longevity, and maintains peak performance for years to come.
