Product Description

The CSF 3947 radiator is a high-efficiency, direct-fit replacement for 2017-2025 Ford F-250 and F-350 Super Duty gas models equipped with the 6.2L, 6.8L, or 7.3L V8 engines.

Its multi-louvered fin structure and cross-flow core maximize coolant circulation, while the integrated heavy-duty oil cooler enhances thermal control for high-load scenarios. Built to exceed OEM pressure and durability standards, the CSF 3947 installs easily using factory hose routing, fan shroud mounting, and oil-cooler connections. Ideal for restoring lost cooling efficiency or upgrading your Super Duty for towing, hauling, or extended service life.
