The SUBARU FORESTER 2.5L Engine, specifically the model number 1The engine is a horizontally opposed, or "boxer," design featuring four cylinders with a displacement of 2,513 cubic centimeters (15.2 gallons). Capable of delivering impressive performance and fuel efficiency, this engine is equipped with a chain-driven dual overhead camshaft (DOHC) system, which optimizes valve timing and duration for robust power output and smooth operation. This engine was manufactured between model years 2009 and 2010 and previously featured the part number 10100BR970. With a nominal output of approximately 170 horsepower at 6,000 rpm and 174 pound-feet of torque at 4,400 rpm, this engine provides more than sufficient power for daily driving and moderate off-road conditions. At the time of its production, this engine was recognized for its reliability, longevity, and responsive performance. It is suitable for applications in a well-maintained, pre-2011 SUBARU FORESTER with a total mileage of around 66,000 miles (106,000 kilometers).

Aftermarket or OEM replacement options are available for those seeking upgrades or enhanced reliability in their SUBARU FORESTER.
The Subaru Forester 2.5L engine with the model number EJ251, produced between 2009 and 2010, is a common choice for those in need of a reliable compact SUV. Here are some pros and cons to consider before making a purchase.
Pros:1. All-Wheel Drive: One of the primary advantages of the Subaru Forester is its standard Symmetrical All-Wheel Drive system. This feature provides excellent traction and stability, making it an ideal choice for drivers in areas with harsh weather conditions or rough terrains.
2. Boxer Engine: The EJ251 engine is a horizontally opposed (boxer) engine. This design reduces vibration and improves the overall balance and smoothness of the vehicle.
3. Durability: Subaru engines are known for their longevity. Many Forester owners have reported reaching 200,000 miles or more with proper maintenance. The EJ251 engine is no exception.
4. Fuel Efficiency: With an EPA estimated fuel economy of 22 mpg city and 28 mpg highway, the Subaru Forester's engine is relatively efficient for its class.
5. Reliability: The Forester 2.5L engine has received positive reviews from both owners and automotive experts. Consumer Reports, for example, rated the engine as being "Reliable."
Cons:1. Maintenance: Subaru engines, including the EJ251, require more frequent oil changes compared to some competitors. The recommended interval for oil changes is every 3,000 to 5,000 miles. This is more frequent than the industry-standard 7,500 miles or longer interval for certain vehicles.
2. Timing Chain Tensioner: There have been reports of timing chain tensioner issues in some EJ251 engines. However, this problem is known to occur more frequently in earlier models. Make sure to inspect the tensioner when considering purchasing a used 2009-2010 Forester.
3. Power Steering: Some drivers have reported issues with the power steering system in their Foresters. The effect is most noticeable when turning at low speeds. The power steering issue is not exclusive to the EJ251 engine but is worth mentioning as a potential concern.
Conclusion:The Subaru Forester 2.5L engine with the EJ251 model number offers several advantages, including superior all-wheel drive, a durable and smooth-running boxer engine, fuel efficiency, and reliability. However, potential buyers should be aware of the need for more frequent oil changes, as well as the possibility of timing chain tensioner issues and power steering concerns.
Recommendation:Considering the pros and cons, I would recommend the Subaru Forester with the 2.5L EJ251 engine as a solid choice for those in need of a reliable compact SUV with excellent traction and stability. However, I suggest inspecting the timing chain tensioner before making a purchase, as well as scheduling frequent oil changes to maintain the engine's longevity. Buyers should also be aware that power steering issues may be a concern but are not unique to the EJ251 engine. Ultimately, with proper care and maintenance, a used Subaru Forester with this engine could provide a satisfying ownership experience.
