Toyota FJ Cruiser Radiator – High Performance from CSF

and it fits the 4Runner too!

From the desert to the mountains, and where the turf meets the surf, Toyota’s FJ Cruiser was ideally designed as the “go-anywhere SUV”. With its 4.0-liter V6 engine that puts out 260 horsepower, and 271lb-ft torque, it has more than enough power to hit the trails, but still got the smooth look to be able to cruise PCH. Some of the earlier released models are coming of age, and the need to replace the original radiator is becoming increasingly apparent. CSF has developed another industry exclusive, a new all-aluminum, high-performance radiator to keep the Toyota FJ Cruiser and 4Runner cool! Meet the Toyota FJ Cruiser Radiator by CSF.

The Premier Toyota FJ Cruiser Radiator

Many FJ’s are getting into the hands of the off-road enthusiast for it’s rugged, yet quirky design, reliability, and off-road capabilities. The performance and aftermarket parts catalog for the FJ continues to grow, and whenever engine performance increases, the burden on the cooling system also rises. It’s one thing driving a racecar and having overheating or leak issues on the track where the safety team can easily tow you back to the pits. Getting stuck on a trail or in the desert in the middle of nowhere can be quite a challenge as things can easily turn into a real-life episode of Man Vs. Wild with Bear Grylls.

Have the peace of mind when out in the middle of nowhere that your more rugged, durable, and more efficient CSF all-aluminum radiator will take you where you want to go… and then get you back!

CSF’s new radiator comes complete with CSF’s industry-leading and exclusive B-Tube technology that increases the heat dissipation by approximately 15% over regular tubes as well as multi-louvered fins to maximize airflow through the radiator core. 100% TIG welded construction ensures a higher level of reliability and durability compared to the OEM plastic tanks, which may become brittle or susceptible to cracking over 5+ years of use, especially when driven in extreme driving conditions. Although the CSF unit has over 50% more capacity than the OEM unit (31mm 1-row B-Tube core versus 27mm 1-row core), it is still a “drop-in fit”, requiring no modifications to install. A true plug-and-play upgrade and replacement solution. Topped off with CSF’s signature 1-hour mirror polish to make it pop! The Toyota FJ Cruiser radiator by CSF is the best you can get.

CSF’s high performance radiator is significantly thicker than the older OEM unit – allowing for more cooling capacity and better heat transfer efficiency.

This FJ radiator also fits the 2nd Generation Toyota Tacoma (2005-2015) with minimal modification to the fan shroud and transmission cooler lines if your truck is an automatic. Here are the steps required to make it fit.

Since the FJ radiator is 2 inches taller than the Tacoma radiator, the bottom lip of the shroud needs to be cut off then re-attached to the bottom of the shroud to prevent the lip from rubbing on the radiator. You can use RTV to reseal and restore the structural integrity of the bottom of the shroud. There will be a small gap between the radiator and the shroud. Using weatherstrip to fill the gaps to maximize airflow through the radiator is optional, but recommended.

Re-drill the top holes of the shroud accordingly.

For Tacomas with automatic transmission, the transmission cooler line brackets need to be bent down approximately ½ inch by hand.

Reconnect radiator hoses and transmission cooler lines (if applicable), fill radiator up with coolant, remember to properly bleed the radiator, tighten the radiator cap and you’re all set!

Shout out to John Farmer for taking the initiative of test fitting the FJ radiator into his Tacoma. He is the one responsible for coming up with the steps required to make everything fit. Thanks John!!

Check out John’s rig, he definitely needed to upgrade his cooling system to go along with his Magnuson Supercharger kit

Our good friend Larry Chen, from SpeedHunters recently upgraded his stock radiator to CSF’s High-Performance Radiator. Larry uses his FJ as a production vehicle to lug all his gear and get to various locations for unique photo shoots and event coverage. In his recent article, he captured some installation photos that shows the comparison of the stock unit versus the CSF High-Performance radiator.

“Our friends at CSF Racing supplied an aluminum dual-pass radiator, which as you can see is much beefier than the stock one. “This will definitely be able to take the abuse that I am going to throw at it, while keeping the FJ cool in the most extreme desert temperatures.” – Larry Chen
