Product Details

The 2-row, 42mm aluminum core in this CSF radiator is designed to handle more coolant and dissipate heat more effectively than stock. CSF uses their exclusive B-Tube technology, which is said to increase heat transfer by about 15% over standard oval welded tubes. This means your engine stays cooler, especially when you're pushing your 4Runner hard.

The fins on this radiator are multi-louvered and about 6.5mm tall, maximizing the surface area that air flows over to carry heat away. The end tanks are made from high-grade aluminum and are TIG welded to the core for a strong, reliable connection, unlike the weaker crimped plastic tanks found on the original equipment. Installation is straightforward as it's designed as a true plug-and-play replacement, meaning no modifications are needed. CSF even includes adhesive foam strips to help seal the fan shroud, which improves airflow efficiency from the fan.

This radiator also features a built-in, heavy-duty transmission fluid cooler with a 5-plate design. This is a significant upgrade, especially if you tow, crawl at low speeds, or have installed larger tires. When you increase tire diameter, your engine and transmission have to work harder, generating more heat. This CSF radiator is built to manage that extra heat, keeping your drivetrain running cooler and more reliably.
