CSF 05-06 Jeep Wrangler Radiator

If you're driving a 2005 or 2006 Jeep Wrangler, keeping your engine cool is crucial, especially if you plan on hitting the trails or overlanding. This all-aluminum radiator from CSF is built to handle the demands of both on-road and off-road use, ensuring your engine stays at its optimal temperature.

CSF has been making radiators for over 50 years, and this one features their exclusive B-tube technology. Instead of a standard oval tube, these B-tubes are specially formed and brazed, making them stronger and allowing for a thinner, lighter aluminum material with better cooling efficiency. This design increases the heat transfer surface area by about 15% compared to regular tubes, creating a dual liquid laminar flow for improved cooling. The radiator also uses ultra-efficient, multi-louvered fins that are precisely aligned to maximize airflow and heat rejection, all tested in a wind tunnel lab.

This CSF radiator is designed as a direct, drop-in fit, meaning you won't need to make any modifications to install it. It accepts all the original equipment components, including the AC condenser, mounting brackets, and fan shroud. The inlet and outlet connections are made to match the factory specs, so you can reuse your original hoses. It also includes a CNC-machined, race-style drain plug with a mirror finish.
