OSC 2779 Replacement Radiator for Subaru Outback 3.0L H6

The OSC 2779 is a premium replacement radiator engineered specifically for 2005-2009 Subaru Outback models equipped with the 3.0L H6 engine. This OE-quality radiator is designed to restore optimal cooling system performance and prevent engine overheating.

Key Features:

• Aluminum core with plastic tank construction for excellent thermal conductivity and durability
• Integrated transmission oil cooler for automatic transmission applications
• Rigorous triple-testing during production: oil coolers tested before tank installation, core tested before assembly, and complete unit tested after assembly
• Premium grade tubes, fins, headers, and tanks engineered for long service life
• Direct drop-in replacement with OE-style fitment for seamless installation
• All necessary fittings and hardware included for easy installation
• Enhanced design features to address original equipment weaknesses and improve cooling efficiency

OSC radiators are manufactured to meet or exceed OEM specifications, ensuring consistent coolant flow and efficient heat dissipation under all driving conditions. Each unit features thermal expansion cuts that allow improved core expansion and contraction during normal heat cycles, along with reinforced B-type tubes for greater pressure tolerance. The deep extrusion header design provides a stronger tube-to-header joint that resists vibration and thermal expansion effects.

Note: Radiator cap sold separately. Always replace antifreeze coolant when installing a new radiator to prevent premature failure.
