CSF 07-12 Jeep Wrangler (JK) Heavy Duty (AT & MT) All-Aluminum Radiator

With over five decades of expertise in radiator manufacturing, CSF stands as a leader in delivering high-quality cooling solutions tailored for demanding environments. The CSF 07-12 Jeep Wrangler (JK) Heavy Duty (AT & MT) All-Aluminum Radiator exemplifies this commitment by combining advanced engineering with robust materials to ensure optimal engine temperature regulation under all driving conditions.

Specifically designed for both on-road reliability and off-road resilience, this heavy-duty radiator is an essential upgrade for Jeep Wrangler owners who require dependable cooling performance during rigorous use. Whether navigating challenging trails, towing heavy loads, or enduring extended drives, this radiator maintains consistent thermal management, thereby protecting your engine from overheating and enhancing overall vehicle longevity.

At the heart of this radiator’s superior performance lies CSF’s proprietary B-Tube Technology. Unlike conventional oval-shaped "O" type tubes, the B-Tube features a unique "B" shape that is seam brazed for enhanced structural integrity. This innovative design enables the use of thinner, lighter aluminum while simultaneously increasing the heat transfer surface area by approximately 15% compared to standard tubes. The result is a more efficient cooling process that mimics the effect of two smaller tubes within the same spatial constraints, facilitating dual liquid laminar flow for improved heat dissipation.

Complementing the B-Tube core, the radiator incorporates ultra-efficient multi-louvered fins, precisely aligned to maximize airflow through the core. Each fin is engineered with a 6.5mm height and a multi-louvered pattern, meticulously calculated and tested in CSF’s wind-tunnel laboratory to optimize heat rejection. This attention to detail ensures that the radiator performs at peak efficiency, even under the most demanding conditions.

The CSF Wrangler radiator is engineered as a true "drop-in fit" replacement, requiring no modifications for installation. This design philosophy guarantees a seamless integration with existing vehicle components. The CNC-machined brackets and fittings provide exceptional durability and precise alignment, while the inlet and outlet connections are designed to match original equipment manufacturer (OEM) specifications. This compatibility allows for the reuse of OEM hoses or aftermarket alternatives without compromising system integrity.

Additional features include an all-aluminum race-style drain plug and a smooth satin finish that not only enhances durability but also provides a refined aesthetic suitable for high-performance applications. The radiator supports all attaching OEM components, including quick-connect hoses, the air conditioning condenser, mounting brackets, and fan shroud, ensuring comprehensive compatibility and ease of maintenance.
