CSF 03-09 Toyota 4Runner V8 / Lexus Lx470 Heavy Duty Aluminum Radiator

The CSF Heavy-Duty All-Aluminum Radiator for the Lexus LX470 and 4th Gen Toyota 4Runner V8 (2003-2009) is engineered to enhance the cooling performance of these rugged SUVs, which are powered by the reliable 2UZ-FE V8 engine. While this engine is celebrated for its durability, the supporting components, particularly the OEM radiator, may not stand the test of time, especially in vehicles over 12 years old with significant mileage. Upgrading to the CSF radiator can help prevent overheating issues that could leave drivers stranded during off-road adventures or daily commutes. Featuring a robust 2-Row 42mm aluminum core, this radiator increases fluid capacity and improves heat dissipation efficiency. CSF's exclusive B-Tube Technology enhances heat transfer by approximately 15% compared to conventional oval welded tubes, ensuring optimal engine temperature management. The design incorporates super-efficient multi-louvered fins, which maximize airflow through the core for unparalleled performance under pressure. Constructed from high-grade aluminum, the end tanks are TIG welded to the core for superior strength, addressing the common failure points found in OEM plastic crimped designs. The CSF radiator is designed for a true plug-and-play drop-in fit, requiring no modifications, trimming, or cutting for installation. To further streamline the installation process, pre-cut double-sided adhesive foam strips are included, creating a secure seal between the fan shroud and the radiator to enhance airflow efficiency. Additionally, this radiator comes equipped with a built-in heavy-duty 5-plate transmission oil cooler, seamlessly connecting to OEM hoses. This upgraded cooler is essential for managing the added heat and stress from towing, low gear crawling, and accommodating oversized tires. As oversized tires reduce effective gear ratios, causing the engine and transmission to work harder, the CSF radiator is specifically designed to handle this increased thermal load, ensuring consistent performance in demanding conditions. Upgrade your Lexus LX470 or 4th Gen Toyota 4Runner with the CSF Heavy-Duty All-Aluminum Radiator, where cutting-edge engineering meets exceptional durability, allowing for reliable operation in both everyday driving and off-road challenges.
