Detailed Description

TYC Radiator 2778 is engineered for Subaru Legacy and Subaru Outback cooling system service where a radiator with an integrated transmission oil cooler is required. The aluminum core, downflow flow configuration, and plate oil cooler design support stable coolant circulation and transmission fluid temperature control. With hose clamp inlet and outlet connections and OE-style dimensions, this radiator is built around the fitment requirements of 2005-2009 Subaru Legacy and 2005-2009 Subaru Outback models. The part number 2778 is also referenced by several aftermarket and Subaru OE numbers, making it easier to match the correct replacement during radiator service.

What This Radiator Helps Address

• Coolant leaks from a damaged or corroded radiator
• Overheating caused by restricted or inefficient heat exchange
• Transmission fluid temperature issues tied to a failed cooler circuit
• Cracked inlet or outlet connections on the original radiator
• Poor cooling performance in high-mileage Subaru Legacy and Outback vehicles

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet diameter, and transmission cooler line style before installation. This radiator uses hose clamp connections for the main hoses and tube-fitting connections for the transmission oil cooler ports. Confirm the vehicle is a 2005-2009 Subaru Legacy or 2005-2009 Subaru Outback application before ordering. Flush the cooling system, inspect hoses and clamps, and refill with the correct coolant mixture after installation.
