Description
CSF’s Heavy-Duty/High-Performance All-Aluminum Radiator is purpose-built for the 03-09 Toyota 4Runner and 06-14 FJ Cruiser, delivering superior cooling for off-road adventures, overlanding, and daily driving. With over 5 decades of cooling expertise, CSF engineered this radiator to keep your engine running at peak performance in any condition.
This radiator features a 2-Row core with CSF’s exclusive B-Tube Technology, which uses specially engineered tubes brazed over the seam rather than welded. The B-tube design increases heat transfer surface area by approximately 15% compared to standard O-type tubes, delivering dual liquid laminar flow within the same space. Ultra-efficient multi-louvered fins are precisely aligned and wind-tunnel tested for maximum heat rejection efficiency.
