Fitment and Application Details

Fits 2021-2024 Ford Edge, N/A, with upgraded heavy duty core. Fits 2021-2023 Lincoln Nautilus, N/A, with upgraded heavy duty core. Fits 2015-2020 Ford Edge, N/A. Fits 2019-2020 Lincoln Nautilus, N/A. Fits 2016-2018 Lincoln MKX, N/A. This part cross-references APDI 8013555 for the same application.

CSF 3793 is a practical choice when replacing a leaking, clogged, or heat-stressed radiator on these platforms. The design follows OEM-style packaging while using an aluminum core for heat transfer and plastic end tanks for factory-style fitment. For 2021-2024 Ford Edge and 2021-2023 Lincoln Nautilus applications, the heavy-duty core specification adds thickness versus the original radiator design.

Common Problems This Radiator Addresses

• Coolant leaks from cracked or aged radiator tanks
• Restricted coolant flow from internal buildup or corrosion
• Engine temperature rise during stop-and-go driving
• Cooling system inefficiency after radiator damage
• Fitment issues when replacing an OE-style radiator on Edge, Nautilus, or MKX models

Installation Notes

Verify inlet and outlet orientation before installation: inlet is 1 5/16 in. on the left and outlet is 1 1/2 in. on the right. Confirm vehicle year, model, and cooling system configuration against the fitment list before ordering. Inspect hoses, clamps, and coolant condition during radiator replacement, and flush the system if contamination is present.
