• 2011-2016 Ford F-550 Super Duty (6.7L V8 Power Stroke Turbo Diesel, 4x2/4x4)

Fitment Notes

• This is the secondary radiator - not the primary engine coolant radiator. The 2011-2016 Ford 6.7L Powerstroke uses a dual-radiator cooling system with separate primary and secondary radiators
• For the primary radiator, see CSF 3601
• Direct OEM replacement - true drop-in fit with no modifications necessary for installation
• Not compatible with the 2017+ Ford Super Duty 6.7L Powerstroke - different radiator design (see CSF 3850 for 2017+ secondary radiator)
• Not compatible with the 6.2L V8 gas engine equipped Super Duty models - different cooling system configuration
• Fits all Super Duty cab configurations (Regular Cab, SuperCab, Crew Cab) and bed lengths
• Fits all trim levels: XL, XLT, Lariat, King Ranch, Platinum

Features

• OEM-specified plastic tank and aluminum core construction matching factory secondary radiator design and materials
• High-performance multi-louvered fin design for maximum cooling efficiency - OEM specification
• Tanks manufactured from virgin-grade engineered plastic resins, glass-filled for added strength and durability
• Gaskets made from special-grade EPDM rubber rated to withstand extreme temperatures
• 100% individually leak tested at the factory at 150% of operating pressure before shipping - each unit is pressure-tested and serial-number certified
• Wind tunnel tested in CSF's laboratory for cooling performance validation
• Vibration-cycle and thermal-cycle tested for long-term reliability
• All components installed, torqued, and tested on the radiator during assembly
• When CSF identifies a weakness in the OEM design or performance, a stronger solution is implemented for class-leading durability
• Industry-best packaging with 10-foot drop test standard

Product Description

The CSF 3602 is a direct OEM replacement secondary radiator engineered for the 2011-2016 Ford F-250, F-350, F-450, and F-550 Super Duty trucks equipped with the 6.7L V8 Power Stroke Turbo Diesel engine. The 6.7L Powerstroke utilizes a dual-radiator cooling system with separate primary and secondary radiators working together to manage the significant heat output of this turbocharged diesel engine - the CSF 3602 replaces the secondary radiator in this system. Built to match the factory radiator's exact dimensions, mounting points, and hose connections, this radiator provides a true drop-in installation with no modifications required, getting your truck back on the road quickly.

CSF manufactures this radiator using OEM-specified plastic tank and aluminum core construction with high-performance multi-louvered fins carefully measured and calculated for this specific application. The plastic tanks are manufactured from virgin-grade engineered resins that are glass-filled for superior strength and resistance to cracking over time. Special-grade EPDM rubber gaskets provide a reliable seal between the tanks and core under the demanding thermal cycling conditions that diesel truck radiators experience daily. Over time, damage from road debris, dirt, bugs, and thermal stress will clog the core and reduce cooling capacity - particularly noticeable on hot days when hauling heavy loads, towing trailers, or operating under sustained high-load conditions typical of commercial and work-site applications.

Every CSF 3602 radiator is individually pressure-tested, serial-number certified, and leak-tested at 150% of operating pressure before leaving the factory. CSF tests every radiator design in-house with their state-of-the-art testing facility that includes wind tunnel, burst pressure, vibration, thermal cycle, and salt spray corrosion testing. When CSF identifies a weakness in either the OEM design or performance, a stronger solution is implemented for class-leading performance and durability. CSF is an ISO-certified cooling system manufacturer with OEM customers around the world and over 50 years of radiator manufacturing experience with more than 30 million units sold - making the CSF 3602 the trusted choice for Super Duty owners who depend on their trucks for towing, hauling, and heavy-duty commercial use.
