CSF 07-18 Jeep Wrangler (JK) Radiator

CSF uses a specially engineered tube shape, called "B-tube" technology, in this radiator for your 2007-2018 Jeep Wrangler. Unlike standard oval tubes, these B-tubes are seam-brazed, making them stronger and allowing for thinner, lighter aluminum. This design increases the heat transfer surface area by about 15%, giving you the cooling efficiency of two smaller tubes in the space of one large one, which CSF calls "dual liquid laminar flow." Combined with ultra-efficient, multi-louvered fins precisely aligned to maximize airflow, this radiator is built to reject heat effectively.

This CSF radiator is designed as a true drop-in fit, meaning no modifications are needed for installation. It accepts all the original attaching components, including your AC condenser, mounting brackets, and fan shroud. The OE-style brackets are CNC machined and welded for solid durability, and the inlet and outlet connections are made to match the factory specifications, so you can reuse your original or aftermarket hoses. Whether you're tackling tough off-road trails, towing a load, or just driving daily, this all-aluminum radiator offers a robust cooling solution for your Wrangler.
