In this review the TRQ Radiator Assembly for the 2007-09 Lexus RX350 is evaluated for fit, function, and value. It is aimed at owners who need a straightforward OE replacement that restores cooling performance without custom modification. The single biggest reason to buy is the direct fit aluminum core that matches OE core thickness and dimensions, delivering reliable cooling and a simple swap-in installation for most DIYers and independent shops.

Key Features

• Complete Transmission Oil Cooler: Includes a plated transmission oil cooler with three cooler plates to support automatic transmission cooling needs.
