Heavy Duty All-Aluminum Radiator | 2010-2024 4Runner

Heavy Duty All-Aluminum Radiator

Protect your engine and transmission under extreme trail conditions with the CSF High-Performance All-Aluminum Heavy-Duty Radiator for the 2010-2024 Toyota 4Runner (5th Gen). Engineered to eliminate heat soak during low-speed rock crawling, desert running, and heavy towing, this radiator replaces fragile OEM plastic-tank units with a rugged, 100% TIG-welded aluminum construction.

Featuring CSF’s exclusive B-Tube Technology and a massive 42mm 2-row core—nearly double the thickness of the factory radiator—this unit delivers maximum heat dissipation, increased fluid capacity, and peace of mind on and off the road.

Key Features

• 42mm Ultra-Efficient Core: Upgrades the thin factory single-row core to a heavy-duty 2-row 42mm core for dramatically increased cooling capacity.
• Exclusive B-Tube Technology: Offers 33% more surface area and heat transfer efficiency compared to standard O-tubes.
• Integrated Upgraded Transmission Cooler: Features an upgraded 4-plate internal automatic transmission cooler in the bottom tank to keep transmission temperatures controlled while towing or hauling.
• 100% All-Aluminum Construction: Fully TIG-welded aluminum end tanks eliminate the failure points of OEM plastic tanks and rubber crimp seals.
• CNC Machined Mounting Brackets: Heavy-duty aluminum brackets and pins replace weak plastic factory mounts to withstand severe off-road vibration.
• True Drop-In Fitment: Installs cleanly without cutting or modifications, maintaining factory fan shroud clearance.
