The 2010-2012 Ram 6.7L primary radiator runs hot once the factory single row is restricted, or it leaks where the tank meets the header. Replace it with the CSF 3529. CSF uses two rows where the factory radiator used one, in the same mounting points.

• Build: The core is 32-3/8 inches by 26-5/8 inches and 1-5/8 inches thick, crossflow, so the 6.7 keeps coolant moving on long grades.
• Tank: Glass-filled plastic tank and EPDM gaskets, leak-tested at 150 percent of operating pressure.
• Hoses: Inlet and outlet are both 1-13/16 inch, inlet on the left and outlet on the right.
• Part number: CSF 3529 crosses OEM 55057089AB.
• Fitment: 2010 Dodge Ram 2500 and 3500, 2011-2012 Ram 2500 and 3500, and 2011-2012 Ram 4500 and 5500 with the 6.7L Cummins.
• Does not fit: 2009-older trucks, which take CSF 3710, and 2013-up trucks, which take CSF 3663.
• Not in the box: The radiator cap is not included. CSF specifies cap 4539 for this core, and the hoses and clamps are not in the box.
• Warranty: CSF lists a 2-year limited warranty for the original owner. The term is on the warranty card in the box.
