The Toyota 4Runner Radiator by CSF is an all-metal 2-row radiator with a 42mm core equipped with a built-in transmission oil cooler. Specifically designed for `03-`09 Toyota 4Runner models, this radiator is engineered to efficiently manage heat dissipation and improve the cooling of your vehicle’s engine and transmission system.

This radiator is expertly crafted with the CSF's exclusive B-Tube technology, enhancing heat transfer by approximately 15% compared to standard oval welded tubes. The multi-louvered fins are designed for maximum airflow through the core, ensuring optimal performance. Made entirely from high-grade aluminum, the end tanks are TIG-welded to the core, providing robust strength that outperforms and outlasts the OEM crimp style, which often incorporates weaker plastic components. For an effortless upgrade, this radiator is a plug-and-play drop-in fit, requiring no modifications to your vehicle. The built-in high-performance 5 plate transmission oil cooler is especially beneficial for demanding conditions such as towing, low gear crawling, or when using oversized tires.
