YITAMOTOR Radiator Compatible with 2003-2009 4Runner 4.0L V6

In this review the YITAMOTOR radiator is presented as a direct-replacement cooling option for owners of 2003-2009 Toyota 4Runner and 2007-2014 FJ Cruiser 4.0L V6 models. The bottom line: this radiator is best for DIY mechanics and repair shops looking for an OE-style unit that prioritizes cooling efficiency and durability, with the important caveat that the radiator cap is not included. The build uses a high-density aluminum core and an integrated aluminum oil cooler, so the primary reason to buy is improved heat dissipation and a straightforward fit for compatible vehicles.

Key Features

• Compatibility: Designed to replace the factory unit on 2003-2009 4Runner and 2007-2014 FJ Cruiser 4.0L V6 models, making part sourcing simpler for those specific vehicles.
• Core Dimensions: A core size of 25.6in x 23.1in provides a substantial radiation area to remove engine heat more effectively than smaller aftermarket cores.
• OE Design: The radiator follows OE layout and mounting points so it installs cleanly and reduces fitment surprises for experienced installers.
• High Cooling Efficiency: High-density aluminum tubes and fins increase heat transfer and rigidity, helping the engine run at stable temperatures under load.
• Leakproof Construction: Seamless welds and glass fiber reinforced nylon PA66 tanks help resist cracking and leaks from heat cycling.
• Packaged Securely: Each unit is leak-tested and shipped with PE foam and multi-layer cardboard for protection in transit.

Who It's For

This radiator is aimed at owners of the listed Toyota 4Runner and FJ Cruiser model years who need a full radiator replacement that matches OE fitment and cooling performance. It suits mechanically comfortable DIYers and independent shops that prefer parts with clear dimensions and a direct-replacement design.

Customers who need a radiator cap included, or who want a lifetime warranty or a brand with long-term service history, may want to consider other suppliers or confirm return policies before purchase. Also, if a vehicle has modified cooling systems or nonstandard transmission lines, verify compatibility first.
