2008-2009 Subaru Legacy 3.0L

The CSF 3142 Radiator is a high-quality OE-style replacement designed for select Subaru Legacy and Outback models equipped with the 3.0L H6 engine (2005–2009 range). Built with an aluminum core and durable plastic tanks, this radiator delivers efficient heat dissipation and factory-correct fitment, making it an ideal replacement for worn or leaking original units.

Featuring a single-row, down-flow design with a core size of approximately 13.75" × 27.16" × 5/8", the CSF 3142 ensures stable operating temperatures during daily driving and maintains consistent coolant flow. Multi-louvered fins improve cooling efficiency, while high-quality EPDM gaskets provide long-term resistance to heat and pressure.

Each radiator is leak-tested before shipping, ensuring reliable performance once installed. With direct-fit compatibility, stock hose alignment, and OE-matched mounting points, the CSF 3142 installs easily without modifications — a perfect solution for restoring the cooling performance of aging Subaru models.
