CSF Radiator

The 3rd Gen Toyota 4Runner has been a long time favorite amongst off-road enthusiasts. Since its release, this generation of 4Runner has been regarded as one of the best off-road platform available. Even at over 20 years of age, you will still see countless of these SUVs both around town and on the trails. Despite their legendary reliability and durability, as these SUVs age there is always room for improvement. While the engines will basically run forever, there are plenty of supporting systems that can use some shoring up. The OEM cooling system is fairly robust and can keep up with most daily driven 4Runners. However, this changes a bit once you start throwing bigger tires on them and pushing them to the limit. That's why CSF developed the new Heavy-Duty All-Aluminum Radiator for the 96-02 Toyota 4Runner.

3rd Gen Toyota 4Runner Heavy-Duty All-Aluminum Radiator (2.7 L4 & 3.4 V6 - AT ONLY

Off-Roading and Overlanding is the fastest growing segment for automotive enthusiasts. As demand for off-road capable vehicles has gone up, older Toyota/Lexus models have become increasingly popular due to their reliability and reasonable prices. Boasting a bulletproof 4.7L V8, 4WD, and ample interior space, it's not hard to see why more and more people are building the J100 Land Cruiser and LX470 for their off-road adventures.

While the J100's 2UZ V8 may be rock solid and can easily keep the SUV running for over 200,000 miles, there are plenty of parts that won't last forever. Although the OEM radiator is well suited for the task of keeping the engine cool in day-to-day driving, it still has its weaknesses. Also, given the age of these SUVs, the original radiator is almost certainly something you want to replace before heading into the wild. CSF is pleased to introduce its latest heavy-duty aluminum radiator for the 1998-200707 Toyota Land Cruiser and Lexus LX470.
• Design and Engineering:
CSF has had unprecedented success with heavy-duty, off-road grade radiators for Toyota 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 is a radiator to fail while you're far from civilization.
• OEM vs CSF:
The 2-row 42mm aluminum core not only increases the fluid capacity of the radiator, but also improves the core's ability to dissipate heat. CSF's Exclusive B-Tube Technology increases the heat transfer by approximately 15 percent 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. Additionally, the built-in oil cooler features a high-efficiency plate design and connects to the OEM hoses.
