Detailed Description

OSC part number 1859 is a replacement radiator for the 1996-1997 Toyota RAV4, designed to match original equipment form and function. It uses a premium aluminum core with plastic tanks, a 13 3/4-inch core height, 27 3/16-inch core width, and 1-inch core thickness. The unit includes a concentric transmission oil cooler and 1 1/4-inch inlet and outlet diameters for OE-style routing.

OSC builds this radiator with cadmium-plated tubes, fitted components torqued to factory specifications, and a die-cut gasket to support a secure seal. The design also incorporates engineering updates such as added fin density and a thicker core to address heat load and durability concerns in higher-mileage vehicles. This makes part number 1859 a practical choice for Toyota RAV4 cooling system repair where original fit and cooling performance matter.

This part cross-references Spectra Premium CU1859 and Koyorad A1859 for the same application.

Common Problems This Radiator Can Address

  • Coolant leaks from a cracked or aging radiator tank
  • Overheating caused by reduced heat transfer efficiency
  • Transmission fluid temperature concerns related to a failing cooler circuit
  • Corrosion or internal wear in an original radiator assembly
  • Poor fit or sealing issues from a previous replacement unit

Installation Notes and Tips

Fits 1996-1997 Toyota RAV4, N/A. Confirm inlet and outlet hose sizing, cooler line routing, and mounting points before installation.

Part number 1859 is a direct-fit style replacement for the listed RAV4 applications.

Quality Assurance

OSC tests the radiator core before assembly, then tests the completed unit again after assembly. The transmission and engine oil cooler circuits are also tested prior to installation into the tank.
