Parts for your 2015 Subaru Forester-Timing belt kit

Does the 2015 Subaru Forester Use a Timing Belt Kit?

For anyone keen on maintaining their 2015 Subaru Forester, understanding the engine's timing system is key. When it comes to timing belts versus timing chains, it's a common question: does this particular model use a timing belt kit or not? After checking technical sources and manufacturer information, it's clear that the 2015 Subaru Forester does not use a timing belt. Instead, this model is fitted with a timing chain.

So why doesn't the 2015 Subaru Forester use a timing belt kit? Simply put, timing chains and timing belts are both designed to synchronise the engine's camshaft and crankshaft, ensuring smooth and precise engine operation. However, Subaru chose to use a timing chain for this model because of its durability and longevity compared to a timing belt.

Timing chains are made of metal and operate inside the engine, lubricated by engine oil. This makes them far more robust and less likely to require routine replacement, unlike timing belts, which are made from high-strength rubber and are exposed to the environment outside the engine. Timing belts wear out over time and need replacing as a preventative measure, usually between 100,000 and 160,000 kilometres depending on the manufacturer's recommendations.

Because of the internal positioning and metal construction, timing chains generally last much longer - often the lifetime of the engine - reducing the need for scheduled replacement kits. This is why the 2015 Subaru Forester, equipped with a timing chain, will not come with or require a timing belt kit as part of its maintenance plan.

So if you were browsing around for a timing belt kit for your 2015 Subaru Forester, you would not find one listed, because it simply does not use that component. Instead, maintenance attention should be directed at other servicing areas such as the chain tensioners, guides, and regular oil changes which help keep the timing chain running smoothly.

That said, timing belt kits are crucial in vehicles that do rely on them. For those models which use a timing belt, the kit usually includes the timing belt itself, tensioners, idler pulleys, and sometimes a water pump. All these components work together to keep the engine timing precise and avoid costly engine damage caused by belt failure.

With that context in mind, here's a look at what a timing belt kit is all about and why it's so important for vehicles that use them (just not this Subaru Forester).

A timing belt kit essentially serves as a comprehensive package to replace all the critical components involved in the engine's timing system at once. Over time, timing belts can wear, crack, stretch or degrade due to heat, age and engine use. If a timing belt fails while the engine is running, it can result in severe engine damage - valves can collide with pistons, causing expensive repairs.

Replacing the timing belt by itself risks missing other worn parts that could cause issues shortly after. A timing belt kit avoids that problem by including associated parts like tensioners and pulleys, which maintain proper belt tension and alignment for smooth operation. Sometimes, the water pump is included because it typically runs off or near the timing belt, and replacing it at the same time saves on labour costs down the track.

For vehicles that require timing belt replacement, service intervals usually range from about 90,000 to 160,000 kilometres or every 5 to 7 years, but always best to check the specific vehicle's service manual. Replacing the kit on schedule keeps the timing components fresh and reliable, preventing failure and extending engine life.

Servicing a timing belt kit is a bit of a labour-intensive job, requiring removal of engine covers and accessories to access the timing components. That is why many VW, Toyota, Honda and other manufacturers recommend changing the whole kit as a preventative measure rather than risk a costly engine failure down the line.

In Australia and around the world, mechanics often advise that timing belt replacement is a 'while-you're-at-it' service, meaning if a belt is due, swap the belt, tensioners, pulleys, and water pump all at once. This approach saves on repetitive labour and avoids future breakdowns.

So, while the 2015 Subaru Forester won't have anything to worry about when it comes to timing belts, since it uses a timing chain system, those with other vehicles should keep timing belt kits on their radar. Paying attention to this part of your vehicle's engine at servicing can save you a whole lot of hassle and money in the long run.
