TRQ Radiator Assembly Aluminum Core Compatible with 03-08 Subaru

In this review the TRQ Radiator Assembly is evaluated as a direct-fit, OE replacement for the 2003-08 Subaru Forester. The bottom line: this radiator is for Forester owners who need a straightforward OE-style swap with an aluminum core and correct inlet/outlet locations, delivering improved cooling performance and clear value compared with many used originals. Installation is typically simple and the unit addresses common overheating concerns while matching OE reference numbers for fitment verification.

Key Features

• Direct Fit: Installs with factory mounting points and matches vehicle-specific fitment to minimize modification or rework.
• OE Replacement: Built to replace the original radiator using OE reference number 45119SA050 so buyers can verify compatibility confidently.
• Aluminum Core: The aluminum core improves heat dissipation compared with older designs, which helps maintain stable engine temperature under load.
• Transmission Cooler Integrated: Includes a concentric transmission oil cooler with bottom-left outlet location to support automatic transmission models.
• Compact Core Dimensions: The single-row, 0.75 in core with 27.19 in width and 14.19 in height balances cooling capacity and under-hood space constraints.
• Aftermarket References: Cross-references like CU2674 and SU3010142 make cross-checking part numbers easier for buyers sourcing replacements.

Who It's For

This radiator is aimed at owners of 2003-2008 Subaru Forester models with 2.5L H4 engines and automatic transmissions who want a like-for-like OE replacement that often cools as well as or better than the original. Mechanics and DIY installers who prefer parts that match OE reference numbers will appreciate the direct-fit nature and aluminum core performance.

Those who should look elsewhere include Forester owners with non-automatic transmissions or vehicles outside the listed years, and buyers who require an upgraded multi-row high-performance cooler; this unit is a single-row, down-flow radiator intended as an OE replacement rather than a race-spec upgrade.

Pros & Cons

Pros

• Good fit and finish that aligns with OE reference 45119SA050 for straightforward installation.
• Aluminum core and single-row design provide reliable cooling and improved heat transfer over many aged originals.
• Clear value for money compared with buying a reconditioned radiator, with many customers reporting strong functionality.
• Integrated concentric transmission cooler supports automatic transmission models without extra plumbing.

Cons

• Some buyers report mixed experiences with assembly hardware; inspect included bolts and O-rings and be prepared to source small parts if missing.
• A few isolated reports of leakage exist, so verify seals and torque points during installation.
