With the Toyota 4Runner and FJ Cruiser becoming some of the most popular affordable off-road vehicles many owners are seeking aftermarket upgrades for these warriors of a vehicle. The 4.0 engine packed under the hood is a workhorse and has been proven through the years to be a reliable platform. One thing these engines lacked was cooling though. Any vehicle can benefit from cooling upgrades but the Toyota 4.0 needed some serious attention to be reliable off-road.
CSF Ultimate Performance Cooling has been engineering aftermarket radiators and specializes in creating a product that can be used as an OE replacement. When taking the 4Runner and FJ out after installing the new CSF radiator, it will be clear that you will never have to worry about cooling again. This radiator uses exclusive B-tube technology. This increases heat dissipation by 15% over the factory and maximizes airflow through the fins. Most OEM radiators are typically an aluminum core with plastic end-tanks which can weaken over years of abuse, especially in extreme off-road conditions.
This new radiator core and end-tanks are constructed of full aluminum. Precision TIG welded all the way around ensures durability and reliability. Even though the core is 50% larger than the factory, the CSF radiator is a drop-in fit for these vehicles. The fully polished radiator adds style and a refined look versus a thin core with black plastic end-tanks that are prone to leaking and becoming an eyesore quickly.
