XDP X-Tra Cool Direct-Fit Replacement Radiator 01-05 6.6L GM Duramax

Is your Duramax running a little warmer lately than it used to? Over time, the radiator will lose its original functionality as sediment and bugs deposit into the pores. Upgrade your radiator for increased cooling to ensure you're never left stranded by an overheated engine. Made for a bolt-on installation, XDP's X-TRA Cool Direct-Fit Radiators feature multiple upgrades for added strength over your OEM unit. Manufactured using special techniques from the HD and Semi industry, the X-TRA Cool Radiators are built to a higher standard and provide you with added protection and reliability. HIGH EFFICIENCY CORE - XDP's X-TRA Cool Radiators are built with High-Efficiency Cores. The upgraded core has more fins per inch with heavy-duty tubes to maximize cooling efficiency in your truck. INTERNAL REINFORCEMENTS - Built with special brazing techniques, the X-TRA Cool Radiators feature internally reinforced end tubes and construction techniques to provide additional strength at the outside corners where the core is most vulnerable. SPECIAL GASKET DESIGN - To allow for expansion, contraction, and to handle the flex in the front end of your truck X-TRA Cool Radiators are built with a proprietary rubber gasket to increase durability and eliminate failure points found in the OE design. REVISED END TANKS - Revised Tanks add strength to the X-TRA Cool Radiator. Paying special attention to the weak points, reinforcement ribs have been added to increase durability. In addition, the plastic mix used to manufacture the end tanks includes a fiber reinforcement to add strength. UPGRADED MOUNTING POINTS - To allow secure mounting in the factory location, and eliminate mounting point failures, the X-TRA Cool Radiators integrated mounting points have been strengthened for durability. TANK ATTACHMENT - Unlike the OEM design, X-TRA Cool Radiator End Tanks are attached with a heavy gauge steel crimp strip. Instead of using aluminum like the factory, the heavy duty crimp eliminates tank and core separation failures that are common with the factory radiator.
