Heavy-duty all-aluminum radiator for the 1996-2002 Toyota 4Runner with the 2.7L or 3.4L engine, featuring a built-in heavy-duty 5-plate transmission oil cooler in the bottom tank that connects to the OEM hoses for towing, low-gear crawling, and oversized-tire use. The 2-row 42mm core uses CSF's B-Tube technology to raise heat transfer about 15% over standard oval tubes, with TIG-welded aluminum end tanks that replace the weaker OEM crimped-plastic design. It mounts in the factory location as a true plug-and-play drop-in with no modifications, and includes pre-cut adhesive foam strips to seal the fan shroud against the radiator.
