The secondary radiator on a 2011-2016 6.7L Powerstroke splits or clogs on its own, and the truck still runs hot if you only change the primary. Replace that smaller radiator with the CSF 3602. It is a 2-row core in place of the factory 1-row secondary, with a quick-connect outlet.

• Build: Core is 20-11/16 inches tall, 39-3/8 inches wide, and 1-5/8 inches thick, so it does not fill the primary opening.
• Pipes: Inlet is 1-1/4 inch on the right and the outlet is 1 inch on the left, with a quick-connect outlet pipe.
• Tank: Glass-filled plastic tank and EPDM seals, leak-tested at 150 percent of operating pressure.
• Part number: CSF 3602 crosses OEM BC3Z8005D and BC3Z8005L.
• Fitment: 2011-2016 Ford F-250, F-350, F-450, and F-550 Super Duty 6.7L Powerstroke secondary radiator.
• Does not fit: The primary radiator, CSF 3601, or 2017-up trucks. The later secondary is CSF 3850.
• Not in the box: The radiator cap is not included, 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.
