Further Information
CSF brings over five decades of radiator manufacturing expertise to the 5th Gen Toyota 4Runner with this heavy-duty, high-performance all-aluminum radiator. Engineered for both on and off-road performance, this radiator is purpose-built for off-roaders, overlanders, and adventurers who demand reliable cooling under extreme conditions.
The radiator features a proprietary 2-Row core with CSF's exclusive B-Tube Technology. Unlike conventional oval "O" type tubes, CSF's specially engineered "B" shaped tubes are brazed over the seam, allowing thinner, lighter aluminum material without sacrificing strength. This design increases heat transfer surface area by approximately 15% while enabling dual liquid laminar flow—delivering the cooling efficiency of two smaller tubes within the same space.
Key Features:
- 2-Row, 42mm ultra high-performance core with exclusive B-Tube Technology
- Ultra-efficient 6.5mm tall multi-louvered fins for maximum surface area contact
