Keep your engine temperatures in check during extreme towing and high-performance driving with the CSF 3601 Heavy Duty Primary Radiator. Designed specifically as a direct-fit upgrade for the 6.7L Ford Powerstroke, this all-aluminum radiator completely eliminates the factory plastic tanks that are notoriously prone to cracking, leaking, and failing under heavy loads.

Whether you are pulling heavy equipment up steep grades or running a high-horsepower street tune, the factory cooling system often struggles to keep up. The CSF 3601 is engineered to dissipate heat faster and withstand the elevated pressures of a hard-working diesel engine, ensuring your truck stays on the road and out of the shop.

Key Features:

• 100% All-Aluminum Construction: TIG-welded aluminum tanks replace weak OEM plastic, drastically increasing structural integrity and burst strength.

• Drop-In Fitment: Designed to utilize the factory mounting points, fan shroud, and original coolant hoses for a straightforward installation without custom fabrication.

• High-Efficiency Core: Maximizes surface area and airflow to provide superior heat transfer and faster recovery times after heavy acceleration or towing.

• Heavy-Duty Durability: Pressure-tested to handle the rigorous demands of tuned engines and heavy payload applications.
