Product Description

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 reasonable prices. The 2003-2009 Lexus GX470 sports a 4.7L 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. Not surprisingly, the GX470 is the Lexus sibling of beloved 4Runner. The 4th Gen V8 4Runner is an equally capable platform for off-roading as well. However, due it’s popularity they are a little harder to find with the big V8.

While the 4Runner/GX470’s 2UZ-FE V8 is one of the most tried and true V8’s from Toyota. It can also be found in the Land Cruiser, Tundra, and Sequoia from this time. However, just because an engine is bullet proof, doesn’t mean the auxiliary components will 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 these SUVs are over 12 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 03-09 Lexus GX470 & 4th Gen V8 Toyota 4Runner.

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 your V8 4Runner/GX470’s radiator to fail on you while you are off-road.

OEM vs CSF

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.
