The 2007 Subaru Legacy came with a 2.5-liter SOHC (Single Overhead Cam) horizontally opposed four-cylinder engine, producing 175 horsepower and 169 lb-ft of torque. This naturally aspirated boxer engine features Subaru’s signature flat-four configuration, which provides a lower center of gravity and better balance compared to traditional inline engines. The engine utilizes a timing belt system with a recommended replacement interval of 105,000 miles. All Legacy models came standard with Subaru’s Symmetrical All-Wheel Drive system, making it capable in various weather conditions. The engine requires regular maintenance including timing belt, water pump, and head gasket attention to ensure longevity.

The 2007 Subaru Legacy shares most parts compatibility with the 2005-2009 fourth generation Legacy models. Engine components, transmission parts, suspension components, and many body panels interchange within this generation. Some electrical components and interior trim pieces may have minor variations between model years. The 2.5L SOHC engine used in 2007 was also used in other Subaru models like the Forester and Outback of similar years, expanding parts availability. However, all-wheel-drive specific components like differentials and driveshafts are typically Legacy-specific. When sourcing parts, it’s important to verify compatibility using VIN numbers, as mid-year changes and trim level differences can affect fitment.

The 2.5L SOHC engine in the 2007 Legacy is moderately reliable but has some well-documented issues. The most significant concern is head gasket failure, which affects most vehicles in this generation between 80,000-120,000 miles. However, once the head gaskets are properly replaced with updated parts, the engine can be quite dependable. Regular maintenance is crucial, including timely timing belt replacement every 105,000 miles and using quality coolant to prevent head gasket issues. The engine responds well to regular oil changes using the correct viscosity. Many owners report these engines lasting well beyond 200,000 miles when properly maintained and after addressing the head gasket issue proactively.
