Radiator Ford 21-Up F-150

The Radiator Ford 21-Up F-150 by CSF Cooling is a direct-fit replacement core engineered for modern Ford fullsize trucks from 2021 through 2024. As a seasoned mechanic, you know that factory radiators endure constant thermal cycling, corrosion, and sediment buildup—especially in trucks used for towing, hauling, or extended idling. This aluminum radiator restores proper coolant flow and heat rejection, preventing overheating and protecting your engine from catastrophic damage.

Built from high-quality aluminum construction, this radiator features a passenger-side inlet and driver-side outlet configuration that matches OEM specifications exactly. The 34.625-inch width and 17.688-inch height ensure optimal fitment within the factory support brackets, while the compact 1.25-inch depth maximizes space efficiency in the engine bay. CSF's multi-pass design and brazed tank construction deliver superior durability and heat transfer efficiency compared to plastic-tank alternatives, making it ideal for sustained load hauling or performance modifications that increase engine output.

This radiator is the go-to choice for F-150 owners tackling cooling system failures, upgrading from a compromised OEM unit, or preparing their truck for heavy-duty work. Installation is straightforward—no modifications required—and the radiator pairs seamlessly with factory hoses, thermostat housings, and upper/lower tank connections. Whether you're dealing with overheating complaints, planning preventive maintenance, or building a reliable workhorse, this CSF radiator delivers the thermal performance and longevity that modern fullsize trucks demand.
