Whether you’re running the robust 2.5L naturally aspirated engine or the powerful 2.0L turbo, off-roading and overlanding can push your vehicle’s cooling system beyond its limits. Steep climbs, traction loss, and added gear weight all increase engine strain and operating temperatures—especially on turbo models—often overwhelming the stock radiator.

CSF’s proven high-performance radiators are built for these demanding conditions. The 2-row, 42mm aluminum core boosts fluid capacity and heat dissipation, while CSF’s exclusive B-Tube technology improves heat transfer by up to 15%. Multi-louvered fins maximize airflow, crucial for low-speed off-road driving where fans do most of the work.

Durable TIG-welded aluminum end tanks replace the weaker OEM plastic design, eliminating a common failure point. Best of all, the radiator is a direct bolt-in replacement requiring no cutting or modifications—keeping your engine cool and your adventure uninterrupted.
