A long-time owner of the Subaru Forester SH, Tahir, has openly shared his experiences with the vehicle, shedding light on issues often left unaddressed within the Subaru community. This particular model is highly valued in the pre-owned market in Kazakhstan, largely due to its classic 4-speed automatic transmission paired with a 2.5-liter FB25 naturally aspirated engine.

Engine Woes and Solutions

According to Tahir, the primary reasons for engine failure in his Forester SH were the use of low-quality oil and overheating. The FB series engines are particularly sensitive to oil quality. Unlike the older EJ series engines, these feature a timing chain and complex variable valve timing systems. Any issues within the lubrication system can quickly lead to oil starvation and damage to internal components.

In Tahir's case, the internal engine damage was so severe that repair was not a viable option. Parts for such engines are expensive, and there's no guarantee of longevity after a rebuild. The most practical solution was to source a replacement engine from another vehicle, often referred to as a 'contract engine'.

Replacing the Engine: A Complex Task

Tahir purchased a low-mileage, newer model engine for 900,000 tenge from an auto parts market in Almaty. While newer engines generally fit older models, some technical challenges arose. For instance, the crankshaft position sensor and its disc differed from the older engine, necessitating the swap of the old engine's disc.

Furthermore, the new engine lacked a mounting point for the power steering system. To overcome this, Tahir utilized the front cover from the old engine and replaced the oil pump with one from the new engine. His key advice is to never discard the old engine immediately, as some of its parts might prove useful later.

After the engine replacement, the vehicle's fuel consumption improved, averaging 9.5 liters per 100 kilometers. While the 2.5-liter engine offers adequate performance for city driving, it lacks the dynamic acceleration of its turbocharged counterparts.

Interior Comfort and Climate Control

The interior of the Forester SH mirrors many crossovers of its era, featuring a blend of dark plastic and semi-velour upholstery. The materials are of good quality, and the dashboard is tightly assembled, contributing to a quiet cabin. Even after 16 years of use, the interior maintains a presentable appearance.

A significant advantage of the cabin is its spaciousness, particularly the ample headroom thanks to the high roofline. The cargo area is moderately sized, comparable to a Hyundai Tucson. The panoramic sunroof is aesthetically pleasing but sees limited use on dusty roads.

One of the main drawbacks is the poor sound insulation. Tire noise is clearly audible inside the cabin, making additional soundproofing a desirable upgrade. The climate control system also presents minor challenges; sometimes, the air flow control valves do not close properly. Additionally, when directing air to the windshield, the air conditioning automatically engages, which can occasionally affect engine performance. The air conditioning system requires annual servicing, as refrigerant oil tends to leak out over the winter months.

Navigating the Purchase of a Used Forester SH

For those considering a used Forester SH, Tahir advises against spending excessive time scrutinizing the suspension and automatic transmission, as these components are readily available and relatively inexpensive in the used parts market. The primary focus should be on the engine.

It's crucial to ascertain the engine's service history and actual mileage. With proper maintenance, the FB25 engine can reliably last over 300,000 kilometers. The most critical factor for this engine is using the correct oil viscosity – exclusively thin oils like 0W-20 or 5W-20 are recommended. Thicker oils, such as 5W-40, are entirely unsuitable. Oil changes should be performed every 5,000-7,000 kilometers. Replacing the spark plugs can also be challenging due to their location in the horizontally opposed engine's cylinder banks, requiring specialized tools for access.

The steering rack and power steering system have known weak points. The front differential may also start making noise under heavy loads. However, the Forester SH's body is remarkably resistant to corrosion. Even after 16 years, there are no signs of rust on the metal, a significant advantage over newer Subaru XV models.

Driving Experience

The driving experience of the Forester SH elicits mixed feelings. On the highway, the vehicle lacks the power of a turbocharged engine. Acceleration to 200 km/h is sluggish, and maintaining such speeds feels precarious. At 160 km/h, fuel consumption increases noticeably.

The suspension system, however, is commendable, effectively handling road imperfections. Off the asphalt, the Forester truly shines. Its signature all-wheel-drive system, combined with intelligent electronics, ensures confident traction on any terrain.

In conclusion, the Forester SH is a practical crossover suited for work, off-road excursions, and family trips. It is a dependable vehicle that, with diligent care, can provide many years of service.
