Heavy-duty all-aluminum radiator for the 4.7L V8 Lexus GX470 and Toyota 4Runner, with a built-in heavy-duty 5-plate transmission oil cooler in the right-side tank that connects to the OEM hoses for towing, low-gear crawling, and oversized-tire setups. 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.
