Product Details

TYC Radiator 2331 is engineered for Subaru Legacy and Subaru Baja cooling-system service where an OE-style radiator with integrated transmission cooling is required. The aluminum core, downflow layout, and concentric transmission oil cooler support efficient heat transfer and fluid temperature control in the radiator assembly. This part cross-references Spectra Premium CU2331 for the same application.

Compatible With 2000-2004 Subaru Legacy, N/A; 2003-2004 Subaru Baja, Primary; and 2006 Subaru Baja, Primary, w/o Sportshift Trans. Use TYC Radiator 2331 when replacing a worn or leaking radiator on these Subaru models and when matching the original hose-clamp connection style and transmission cooler layout matters.

What This Radiator Helps Address

• Coolant leaks from a damaged radiator core or tank
• Overheating caused by restricted coolant flow
• Transmission fluid temperature concerns tied to the radiator cooler circuit
• Corrosion or age-related deterioration in the original radiator
• Fitment issues when replacing an OE-style Subaru radiator

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet diameter, and transmission cooler line connection style before installation. This radiator uses hose clamp inlet and outlet connections and tube-fitting transmission cooler ports, so matching the vehicle’s original plumbing is important. Confirm application details for 2006 Subaru Baja models, since this listing applies to vehicles without Sportshift transmission.

Quality Assurance

TYC Radiator 2331 is built to meet replacement needs for Subaru cooling-system service with application-specific fitment and integrated transmission cooling. It is listed for Subaru Baja and Subaru Legacy applications and follows the original-style radiator configuration for the covered vehicles.
