Product Description

The CSF 7085 is a heavy-duty, all-aluminum high-performance radiator engineered specifically for the 2010-2022 Toyota 4Runner (5th Generation) with the 4.0L V6 or 2.7L I4 engine. It represents a substantial upgrade over the factory plastic-tanked OEM radiator, featuring CSF's exclusive B-Tube technology in a 2-row 42mm core - doubling the effective core depth compared to the OEM 1-row 22mm design. This increase in core capacity, combined with ultra-efficient 6.5mm multi-louvered fins, delivers significantly improved heat rejection for 4Runner owners who tow, run lift kits, off-road in demanding conditions, or simply want a more durable long-term cooling solution.

The upgraded 4-plate automatic transmission oil cooler integrated into the bottom end tank helps manage transmission temperatures during extended towing and low-speed trail driving. The entire unit is built from all-aluminum with 100% TIG-welded construction, CNC machined mounting brackets for a precise fit, and finished with CSF's signature one-hour mirror polish. It installs as a true drop-in replacement using all factory mounting points - no modifications required - and is backed by a 2-year limited warranty.
