Detailed Description

Built for Ford Super Duty cooling service, the CSF 3601 radiator is designed around OE-style plastic tanks and an aluminum core for a direct-fit replacement approach. The cross-flow layout and 2-row core configuration support efficient coolant flow and heat dissipation, while the quick-connect pipe design helps match factory-style hose routing on 2011-2016 Ford F-250 Super Duty and Ford F-350 Super Duty trucks. CSF manufactures radiators to controlled standards and validates cooling performance through lab testing, making this radiator a practical choice for restoring proper engine temperature control.

This part cross-references Spectra Premium CU13230 for the same application.

What It Helps Address

• Overheating caused by a worn or restricted radiator core
• Coolant leaks from aging plastic tank construction
• Reduced cooling efficiency in heavy-duty Ford Super Duty use
• Factory radiator replacement needs after damage or corrosion
• Temperature instability during towing, hauling, or stop-and-go driving

Installation Notes and Tips

Verify inlet and outlet orientation before installation: this radiator uses a left inlet and right outlet layout. Confirm core dimensions, hose connection style, and vehicle fitment for your specific 2011-2016 Ford F-250 Super Duty or Ford F-350 Super Duty before removal of the original unit. Transfer any required OE-style components from the existing cooling system as needed, and inspect hoses, clamps, and coolant condition during replacement.
