Detailed Description

This Global Parts radiator, part number 2331C, is engineered for Subaru Legacy, Subaru Outback, and Subaru Baja applications that require a down-flow cooling layout. The aluminum core helps dissipate heat efficiently, while the plastic tank construction matches common OE-style radiator design. With a 1.5-inch inlet and outlet and a single-row core, this radiator is built to replace the original cooling unit in vehicles listed in the fitment data. This part cross-references DENSO Auto Parts 221-3601 and Spectra Premium CU2331 for the same application.

Vehicle Fitment

• Fits 2003-2006 Subaru Baja, N/A
• Fits 2000-2004 Subaru Legacy, N/A
• Fits 2000-2004 Subaru Outback, N/A

What This Radiator Helps Address

• Engine overheating caused by a failing radiator core
• Coolant leaks from cracked or aged radiator tanks
• Transmission cooling concerns when the factory cooler is part of the radiator assembly
• Restricted heat transfer from corrosion or internal buildup
• Cooling-system replacement needs on Subaru Legacy, Outback, and Baja models

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet size, and transmission cooler line connection style before installation. This radiator uses tube-style transmission cooler fittings and a down-flow configuration, so matching the original layout is important for proper fitment. Always inspect hoses, clamps, and coolant condition during replacement, and confirm the vehicle’s transmission setup against the fitment listing for your Subaru Legacy, Outback, or Baja.

Quality Assurance

Global Parts supplies replacement cooling components for direct-fit service applications. Part number 2331C is built to match the listed vehicle coverage and cooling-system requirements for the confirmed Subaru fitment range.
