Detailed Description

The Global Parts 13870C radiator is a direct-fit cooling system replacement for Subaru Legacy, Subaru Outback, and Subaru Impreza applications listed above.

This part cross-references BBB Industries 13870 and UAC RA13870C for the same application.

Common Problems This Radiator Can Address

  • Coolant leaks from a cracked or aging radiator tank
  • Restricted cooling performance from a clogged or damaged core
  • Overheating caused by radiator failure
  • Temperature instability during daily driving or stop-and-go traffic
  • Loss of cooling efficiency after OEM radiator wear

Installation Notes and Tips

Verify hose diameter, mounting points, and transmission-cooler requirements before installation. This radiator does not include a radiator cap, thermostat, engine oil cooler, or transmission oil cooler, so reuse or source those components as needed for the vehicle. Flush the cooling system, inspect hoses and clamps, and refill with the correct Subaru-approved coolant after installation. Fits 2021-2025 Subaru Legacy, N/A; fits 2020-2025 Subaru Outback, N/A; fits 2024-2025 Subaru Impreza, N/A.
