CSF High-Performance All-Aluminum 2-Row B-Tube Radiator for 2007-2018 Jeep Wrangler JK

Fits all 2007-2018 Jeep Wrangler JK models, including Rubicon, Sahara, Sport, and Unlimited trims.

The CSF 7036 is a heavy-duty, high-performance cooling solution engineered for the rigors of off-road and overland use. This all-aluminum radiator features a 42mm 2-row core utilizing CSF’s exclusive B-Tube technology. Unlike standard "O" type tubes, the B-Tube design is seam-brazed for superior structural integrity, allowing for thinner, lighter aluminum with increased heat transfer surface area—providing approximately 15% better cooling efficiency than conventional designs.

Designed as a true drop-in replacement, this radiator requires no modifications for installation. It is precision-engineered to accept all factory components, including "quick connect" hoses, the AC condenser, mounting brackets, and the OE fan shroud. Each unit is finished in a smooth satin and features CNC-machined fittings for a leak-free, factory-level fit.
