( CSF #7214 )

Off-Roading and Overlanding has arguably become the most popular motorsport activity among automotive enthusiasts. As demand for off-road capable vehicles has gone up, less traditional models have become increasingly popular. Lexus has been making huge waves here due to their reliability and value. The 2010+ Lexus GX460 sports a 4.6L V8, 4WD, smooth ride, and ample interior space. Pretty much everything anyone who’s not a jeep purist would look for in an off-road platform.

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. With that being said, CSF is pleased to introduce its latest Heavy Duty Radiator for the 2010+ Lexus GX460.

Design & Engineering

CSF has a great track record with heavy duty, off-road grade radiators for Toyota/Lexus trucks and SUVs. With most off-road vehicles, the factory cooling components can easily become over stressed. This may be due to the demanding stress on the engine while climbing or dirt clogging up some of the cooling fins. The last thing you want or need is a radiator to fail on you while you’re far from civilization.


The 2-Row 42mm aluminum 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 aluminum 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.
