CSF 3597 Radiator

CSF 3597 Radiator Overview

The CSF 3597 is an OE-style radiator built with a plastic tank and aluminum core for direct replacement cooling performance. It is engineered for vehicles that need a cross flow design with right-side inlet and left-side outlet routing.

Compatible with 2013-2019 Ford Flex and 2013-2019 Lincoln MKT equipped with the tow package, this radiator is built to match the factory-style layout for those applications. The CSF 3597 is also cross-referenced to Bosch 13522 for the same application.

Product Details

CSF manufactures radiators to high-performance standards and validates cooling performance through laboratory wind tunnel testing. The brand supplies a wide range of radiator designs for many vehicle platforms, and the CSF 3597 follows that approach with an OE-style plastic tank and aluminum core layout. This radiator is intended for Ford Flex and Lincoln MKT models with tow package fitment, where correct hose routing, core size, and cross flow configuration are important for proper cooling system service.

Common Cooling System Issues This Radiator Can Address

• Cracked or leaking radiator tanks
• Corrosion or internal blockage in the cooling core
• Overheating caused by reduced coolant flow
• Damaged inlet or outlet connections
• Cooling system service needs on tow package-equipped Ford Flex and Lincoln MKT models

Installation Notes

Verify radiator dimensions, inlet and outlet placement, and tow package fitment before installation. This unit uses a right-side inlet and left-side outlet, so hose routing should match the original configuration. Inspect related cooling system components, including hoses, clamps, and coolant condition, during replacement. The radiator cap is not included.
