CSF Radiators - Aluminum

While the GX460's 1UR-FE V8 has been around for over a decade and proven to be an absolute tank of a motor, the auxiliary components can't last forever. Although the OEM radiator is well suited for the task of keeping the engine cool in day to day driving, the OEM radiator still has its weaknesses. Also, given that many of these SUVs are over 10 years old with a fair bit of mileage on them, it might be a good idea to replace that original radiator before it leaves you stranded in the wilderness. While some may opt for a simple OEM replacement, CSF knows many enthusiasts are always looking to improve their vehicles. The 2-Row 42mm core not only increases the fluid capacity of the radiator, but also improves the cores ability to dissipate heat. CSF's Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance. End tanks are made from high grade and TIG welded to the core for extra strength. In contrast, the OEM crimped onto plastic end tank design is much weaker and creates a weak point where failure is more likely. Because the CSF radiator is designed as a true plug-and-play drop-in fit application, installation requires absolutely no modifications, trimming, or cutting. CSF even includes pre-cut double sided adhesive foam strips to help seal the fan shroud against the radiator. This improves airflow efficiency off the fan. Additionally, the radiator features a built-in transmission oil cooler. The transmission cooler is a heavy-duty high-performance 5 plate design that connects to the OEM hoses. The upgraded built in cooler is great dealing with the added heat and stress from towing, low gear crawling, and vehicles equipped with oversized tires. While many understand the impacts of oversized tires, it is always good to provide extra incite. By increasing the diameter of your tires, you are reducing the effective gear ratio. This means the engine and transmission have to work harder to move the tires. Obviously this will end up generating excess heat, but the CSF radiator is designed to handle it.
