Product Description

The Mishimoto MMRAD-GX460-10 is a high-performance, direct-fit aluminum radiator crafted specifically for Lexus GX460 models equipped with the 4.6 L V8 engine. Designed to improve cooling efficiency and reliability for rugged use - whether highway cruising or off-road duty - this radiator offers roughly 40 % more coolant capacity and increased surface area compared to the OEM plastic unit :contentReference[oaicite:8]{index=8}.

Constructed from TIG-welded aluminum with precise CNC-machined fittings and a billet fill neck, the unit includes a liquid-to-liquid stacked-plate transmission cooler built into the tank for optimal fluid temp control. A magnetic drain plug helps capture metallic debris for extended system longevity. This radiator drops straight into the GX460 without any trimming or modifications - though Mishimoto notes minor upper shroud clip changes may occur due to the thicker core, which does not impact reliability :contentReference[oaicite:9]{index=9}.

Installation is straightforward: remove OEM radiator, swap in the Mishimoto unit using supplied mounting hardware, and reconnect all hoses and fittings. Performance-minded drivers and Lexus owners seeking improved cooling capacity and breathing room for towing or off-road loads will appreciate the robustness of this design. Coverage is confirmed through 2023; suitability for 2024-2025 model years is currently unconfirmed.
