Description

The Koyorad A2777 radiator is engineered as a direct OE aftermarket replacement for 2008-2011 Subaru Outback Sport models equipped with the 2.5L H4 non-turbo engine and automatic transmission. Constructed with a durable aluminum core and plastic tanks, this radiator is designed for optimal coolant flow and efficient heat transfer, meeting stringent quality control standards set by Koyorad's ISO 9001 certified factories. This radiator boasts a core height of 13.375 inches, a width of 27.8125 inches, and a thickness of 0.625 inches, with a single row design. It also features an integrated transmission oil cooler (TOC) with 3 plates and includes the necessary TOC fittings for installation. The inlet and outlet diameters are both 1.5625 inches. Koyorad emphasizes the importance of proper installation and maintenance. It is recommended to perform a complete cooling system flush and refill with the correct coolant type specified in the vehicle's owner's manual. Failure to do so can lead to corrosion, leaks, and premature wear. Koyorad also suggests considering the replacement of radiator hoses, clamps, thermostat, and radiator cap during routine maintenance to ensure the longevity and optimal performance of the cooling system.
