CSF 3rd Gen Raptor & 14th Gen F-150 Heavy-Duty All-Aluminum Radiator (2021-2026)

Upgraded cooling systems are not just for off-road rigs and big haulers. Even basic mods/upgrades like oversized tires can increase strain on your engine in adverse conditions. The CSF Radiator provides extra protection that:

• Extends engine life by maintaining optimal coolant temperatures
• Improves towing capacity by enhancing cooling efficiency
• Eliminates performance limitations during demanding driving conditions
• Provides peace of mind with superior construction and durability

When engine coolant overheats, performance suffers and you are forced to stop driving or risk a cooling system failure. CSF & Full-Race engineers identified this vulnerability during extensive real-world testing of F-150 and Raptor models under demanding conditions. Having to stop and wait for your engine to cool down is more than just an inconvenience, it is a limitation that shouldn't exist in modern trucks. Especially not a Raptor.

Design & Engineering

An upgraded radiator helps eliminate the concern of overheating. This advanced design features larger 2-Row, 42mm aluminum cores which increases the fluid capacity of the radiator and greatly improves heat dissipation. CSF's Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the ultra-efficient multi-louvered 5mm fins maximize airflow through the core for the best possible performance. The result is a dramatic temperature reduction under all driving conditions.

Key Features:

• 50% larger core volume than the factory radiator
• 20-25% increase in heat transfer efficiency using CSF's exclusive 5mm Fin Technology
• 100% TIG welded Aluminum construction (compared to plastic end tanks crimped)
• Perfect for daily driving, towing, and off-road adventures

5mm Core Upgrade

While the first prototypes with CSF's 6.5mm fin performed extremely well in testing, CSF always seeks to offer the ultimate cooling solution. Before going into final production the design was updated to incorporate CSF's latest 5mm fin technology which was introduced at the end of 2023. This new core specification offers even more heat transfer area and thermal efficiency than the tested prototypes. CSF is confident this radiator is ready to take on the most demanding conditions in the world.

Plug and Play Installation

CSF designed these Radiators to easily replace the OEM units. The Plug-and-Play "Drop-in Fit" installation takes under an hour and greatly improves the reliability and longevity of your engine.
