Koyorad has released an all-aluminum high-performance radiator for the fifth generation (2010–2020) 4Runner with a 4.0L V6. Koyorad’s high-density HyperCore measures 36mm thick, a 33% increase over the OEM unit, which boosts the cooling system’s heat capacity and endurance under extreme use. This radiator is a long-lasting upgrade and perfect replacement for an old and brittle OEM plastic tank radiator with TIG-welded all-aluminium tanks. Designed for serious off-road enthusiasts, the internal automatic transmission (AT) cooler has been purposefully omitted. An external transmission cooler (not included) will be necessary, which allows for visual inspections of the cooler itself and can be upsized and upgraded to offer improved transmission performance in the field. Since the internal AT cooler has been removed, the radiator will have zero risks of coolant and transmission fluid breech which can cause catastrophic engine and drivetrain damage. Advanced engineering and design, impeccable TIG welds, proficiency in furnace brazing, and triple pressure testing for quality have earned Koyorad an excellent reputation in performance cooling worldwide.

  • No internal AT cooler eliminates the chance of coolant and transmission fluid breech on AT vehicle
  • TIG-welded and furnace brazed for strength

  • Manufactured and triple pressure tested in Koyorad’s private ISO 9001 certified factory
