All-Aluminum Heavy-Duty Radiator for the 5th Gen Toyota 4Runner.

CSF has answered the call for increased performance and durability with its new 5th Gen Toyota 4Runner All Aluminum Heavy-Duty Radiator. It’s the perfect answer to upgrading and safe-guarding against the weak OEM radiator with plastic end tanks.

OEM plastic/aluminum radiators make sense to produce in mass quantities to get cars and trucks through the assembly line and onto the road, but they come with many limitations – especially when drivers take their SUVs and trucks off-road or drive them in extreme conditions. After several years, the plastic tanks can start to become brittle from excessive heat cycles, can crack under heavy vibration, or can burst from extreme pressures and temperatures (including cold starts in freezing temperatures). 

CSF's 100% TIG welded all-aluminum end tanks prevent potential leakage when compared to the weaker plastic tanks that utilize a rubber gasket and a crimp design to seal.


  • 2 row, 42mm ultra high-performance core featuring CSF's exclusive B-tube technology.
  • Core features ultra-efficient, 6.5mm tall fins with a multi-louvered design for maximum surface area contact.
  • Upgraded 4-plate automatic transmission cooler built into bottom end tank.
  • Individually leak and pressure tested.
  • CNC machined mounting brackets for superb fit and durability.
  • 100% all aluminum TIG-welded construction.
  • True “drop-in-fit” requires no modifications to install.
  • 1 hour “mirror finish” hand polish.
  • 2 year limited warranty.
