CSF 05-06 Jeep Wrangler Heavy Duty (AT & MT) High-Performance All-Aluminum Radiator

With over 50 years of expertise in radiator manufacturing, CSF stands as a benchmark in delivering reliable and high-performance cooling solutions. The CSF 05-06 Jeep Wrangler Heavy Duty (AT & MT) High-Performance All-Aluminum Radiator is engineered to meet the rigorous demands of both on-road and off-road driving, ensuring your Jeep Wrangler maintains optimal engine temperature under all conditions. This radiator is an essential upgrade for off-road enthusiasts, overlanders, and adventurers who require durable and efficient cooling components to support intense driving scenarios. This radiator features a robust 2-Row 42mm core that incorporates CSF’s exclusive B-Tube Technology. Unlike conventional oval-shaped “O” tubes, the innovative “B” shaped tubes are precision-engineered and seam-brazed to create a stronger, lighter, and more thermally efficient design. This unique tube shape allows the use of thinner aluminum, enhancing heat transfer efficiency without compromising structural integrity. The inlet positioned in the middle of the tube, combined with seam brazing, increases the heat transfer surface area by approximately 15% compared to traditional tubes. This design effectively doubles the cooling efficiency within the same spatial constraints by enabling dual liquid laminar flow, which optimizes coolant movement and heat dissipation. Complementing the B-Tube design, CSF employs ultra-efficient multi-louvered fins, meticulously aligned to maximize airflow through the radiator core. These fins, with a height of 6.5mm, are engineered to provide maximum surface area contact, significantly improving heat rejection. Each fin specification is tailored for the specific application and validated through rigorous testing in CSF’s wind-tunnel laboratory, ensuring superior cooling performance under demanding conditions. The CSF Wrangler radiator is designed as a true “Drop-in fit,” requiring no modifications for installation. The OE-style brackets are CNC machined and welded to guarantee exceptional durability and precise fitment. Inlet and outlet connections are CNC machined to match original equipment specifications, allowing the reuse of OEM hoses or compatible aftermarket components seamlessly. This ensures a hassle-free upgrade experience while maintaining compatibility with factory-installed parts such as the AC condenser, mounting brackets, and fan shroud. Whether your driving involves off-road trails, towing heavy loads, or routine daily use, the CSF Heavy Duty/High-Performance Radiator provides dependable cooling performance. CSF’s commitment to quality and reliability makes it the preferred choice for those seeking to enhance their Jeep Wrangler’s cooling system with a product that meets stringent automotive standards.
