CSF Heavy-Duty All-Aluminum Radiator 1996-2002 Toyota 4Runner

Design & Engineering CSF has a great track record 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 can be due to a variety of things. The demanding stress on the engine while climbing or dirt clogging up some of the cooling fins are the most common culprits. The last thing you want or need is your 4Runner’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 found on many other aluminum radiators. Additionally, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance. The end tanks are made from high grade aluminum and TIG welded to the core for extra strength
