Product Details

One Stop Solutions part number 13461 is a replacement radiator for Subaru Legacy and Subaru Outback models from 2015 through 2019. It is built around OE-style dimensions and assembly practices, with components fitted to factory specifications for consistent installation and cooling-system service. The radiator uses a PA core material and a 16 mm, 5/8 in. core thickness, with no integrated engine oil cooler or transmission oil cooler.

The design includes engineering updates aimed at improving cooling performance and service life on higher-mileage vehicles. Additional fin density and a thicker core are used to address heat load in demanding driving conditions. This part cross-references Spectra Premium CU13461 for the same application.

Common Replacement Reasons

• Coolant leaks from a damaged or aging radiator
• Overheating caused by restricted coolant flow
• Corrosion or wear in the radiator core, tanks, or headers
• Reduced cooling efficiency in a high-mileage Subaru Legacy or Outback
• Fitment issues after a prior repair or collision-related replacement

Installation Notes

Verify vehicle fitment by year and model before installation. This radiator is a direct replacement for the listed Subaru Legacy and Subaru Outback applications and is intended to install without modification when the cooling system is in standard configuration. Confirm that the vehicle does not require an integrated engine oil cooler or transmission oil cooler, since this unit is specified with none.

Inspect hoses, clamps, and related cooling-system components during replacement to help ensure proper sealing and operation. The cap is not included, so reuse or replace the cap as needed based on the vehicle’s existing setup.

Quality Assurance

OSC radiators are tested during production, including checks of the cooler circuits before tank installation, core testing before assembly, and a final test after assembly. The design also incorporates updates intended to correct original failure points and improve durability in long-term service.
