Detailed Description

This radiator is built to match original equipment form and function for the Subaru Forester cooling system. OSC uses engineering updates such as improved fin density, a thicker core profile, and an integrated transmission cooler to address heat load and durability concerns in higher-mileage vehicles. Part number 13021 is also cross-referenced to APDI 8012674 and Spectra Premium CU2674 for the same application.

For buyers searching for a 2006 Subaru Forester radiator, 2007 Subaru Forester radiator, or 2008 Subaru Forester radiator, this unit provides a direct-fit replacement solution with the correct downflow layout and OE-style connection sizes. The radiator core is made from PA material, with plastic tanks and a concentric cooler arrangement where originally equipped.

What This Radiator Helps Address

• Engine overheating caused by a worn or restricted radiator
• Transmission temperature concerns related to an aging cooler circuit
• Coolant leaks from cracked tanks, weakened seams, or gasket failure
• Reduced cooling efficiency from clogged or damaged internal passages
• Fitment issues from non-OE-style replacement parts

Installation Notes and Tips

Confirm the radiator dimensions, inlet and outlet sizes, and downflow configuration before installation. Transfer any required vehicle-specific components from the original assembly as needed, and inspect hoses, clamps, and coolant condition while the cooling system is open. Proper system bleeding and a pressure check after installation help verify sealing and cooling performance.

Quality Assurance

OSC tests the transmission and engine oil coolers before tank installation, checks the core before assembly, and tests the completed radiator again after assembly. Each unit is individually pressure tested to verify sealing and build quality.
