In this review the AUTOSAVER88 radiator is evaluated for owners of 2003-2009 Lexus GX470 and 2003-2009 Toyota 4Runner with the 4.7L V8. The bottom line: this is a straightforward, direct fit replacement that delivers strong cooling performance thanks to a high density aluminum core, and it is best for owners who want an OE-style radiator without paying dealer prices. Confirm vehicle compatibility before ordering, since correct fitment is the single most important reason to choose this unit.

Key Features

• Compatibility: Built to match fitment for 2003-2009 Lexus GX470 and 2003-2009 4Runner 4.7L V8, reducing the need for modifications.
• OE Replacement: Replacement OEM part numbers 1640050300 and TO3010275 are referenced to help verify correct application.
• High density core: The aluminum core uses multi-louvered fins to improve cooling efficiency in hot or cold weather.
• Leakproof materials: A combination of a high-grade plastic tank and aluminum core is used, with leak testing performed before shipping to improve longevity.
• Direct fit installation: Designed as a direct fit OE standard radiator to simplify installation for technicians or experienced DIYers.
• Complete unit: Package includes one new complete radiator and a user manual so the buyer receives a ready-to-install assembly (radiator cap not included).

Who It's For

This radiator is aimed at owners of Lexus GX470 and Toyota 4Runner with the 4.7L V8 who need a full radiator replacement that closely matches OEM design and cooling performance. It suits budget-conscious buyers who still want a core and tank assembly built to OE standards and tested for leaks.

It is not ideal for someone who expects an included radiator cap or who prefers to avoid professional installation; buyers with limited mechanical experience should budget for a shop install.
