Product Details

This TYC Radiator line part is engineered around the listed core dimensions and connection layout for a direct-fit cooling system service on the Toyota RAV4. The radiator uses an aluminum core, 1.26-inch inlet and outlet diameters, and a concentric transmission cooler with tube-fitting connections. For buyers searching for a 1996 Toyota RAV4 radiator, 1997 Toyota RAV4 radiator, or TYC 1859 radiator replacement, this unit matches the confirmed fitment and cooling configuration.

This part cross-references Toyota 16400-7A122 for the same application.

Common Cooling System Issues It Can Address

  • Coolant leaks from a damaged or corroded radiator
  • Overheating caused by restricted coolant flow
  • Transmission fluid temperature concerns tied to a failing cooler circuit
  • Cracked plastic tanks or weakened radiator seams
  • Reduced cooling performance from an aging OE radiator

Installation Notes and Tips

Verify the radiator dimensions, inlet and outlet sizes, and transmission cooler line style before installation. Confirm hose-clamp connections and tube-fitting cooler ports match the vehicle’s existing setup on the Toyota RAV4. Flush the cooling system and inspect hoses, clamps, and coolant condition before installing the new radiator to help prevent contamination from carrying into the replacement unit.

Quality Assurance
