CSF OEM Plastic Radiator for 2017+ Ford F-250 & F-350 Super Duty 6.2L & 7.3L

The CSF OEM Plastic Radiator is esigned specifically for the 6.2L V8 and 7.3L V8 engines, this radiator delivers reliable, efficient cooling for demanding tasks like towing, hauling, or off-road driving. Engineered to meet or exceed OEM standards, this radiator ensures a perfect fit, seamless installation, and long-lasting durability, making it the go-to choice for Ford truck owners who need dependable performance under tough conditions.

Why Choose a CSF Radiator?

This radiator stands out for its precise engineering and robust construction, crafted to handle the intense cooling demands of your Ford Super Duty. With a lightweight yet durable plastic tank and aluminum core design, it effectively dissipates heat to prevent engine overheating, prolonging the life of your vehicle. Its direct-fit design eliminates the need for modifications, and the included high-efficiency oil cooler enhances overall cooling performance. Whether you're navigating rugged terrain or pulling heavy loads, the CSF 3947 ensures your engine stays cool and reliable.

Why CSF Stands Out

CSF has been a trusted name in cooling systems for over 50 years, with more than 30 million units sold worldwide. Their ISO/TSO-certified factories produce radiators that meet the same high standards as those supplied to OEMs for brands like Ford, Honda, and Toyota. Each CSF 3947 radiator is wind tunnel tested for cooling efficiency and subjected to a 10-foot box drop test to ensure packaging protection during shipping. With a focus on quality and performance, CSF delivers a radiator that keeps your Ford Super Duty running smoothly in any condition.

Installation Notes

  • Easy Installation: Designed as a direct replacement for the factory radiator, ensuring a perfect fit.
  • Pre-Installation Inspection: Inspect the radiator for any damage before installation, as post-installation damages (e.g., bulging tanks or warped core due to high pressure or temperature) are not covered under warranty.
  • Professional Installation Recommended: Ensure proper installation by a certified technician to maintain warranty eligibility.

Trust CSF for Your Ford Super Duty

The CSF 3947 radiator is the ideal choice for 2017-2019 Ford F-250 and F-350 Super Duty owners seeking a reliable, high-performance cooling solution. Its precision engineering, durable materials, and rigorous testing make it a standout option for keeping your truck’s engine cool and efficient, no matter the task. Order the CSF 3947 radiator today and experience the difference in performance and reliability for your Ford Super Duty.
