Understanding the Timing Belt in the 2013 Subaru Forester

The 2013 Subaru Forester is a well-regarded compact SUV known for its reliability and all-wheel-drive prowess. When it comes to the engine's internals, many vehicle owners find themselves wondering about the timing belt and whether it plays a role in their Forester's operation. It's an important question since the timing belt is a critical component in many engines, responsible for synchronising the crankshaft and camshaft to ensure the engine's valves open and close at the right times.

To jump straight into it, the 2013 Subaru Forester does not use a timing belt. Instead, it comes equipped with a timing chain. This distinction is important because the timing chain and timing belt serve the same fundamental purpose but differ significantly in terms of materials, durability, and maintenance requirements.

Now, why doesn't the 2013 Subaru Forester use a timing belt? Subaru has favoured timing chains over belts in many of its modern engines, especially the flat-four boxer engines found in the Forester. The timing chain offers several advantages, primarily in terms of longevity and reliability. Unlike a timing belt, which is made from rubber and requires periodic replacement (usually every 100,000 kilometres or so), a timing chain is made from metal and designed to last much longer - often for the lifetime of the engine.

This feature appeals to many drivers because it cuts down on maintenance costs and inconvenience. Timing chains are less likely to snap or stretch prematurely, which can lead to serious engine damage. So Subaru's approach means Forester owners can relax a bit more without worrying about the timing belt replacement intervals that come with many other vehicle models.

Although timing chains are considered more durable and generally require less routine maintenance, they are not totally maintenance-free. Over time and many kilometres, a timing chain can stretch or the tensioners and guides can wear out, which may cause noise or performance issues. But this generally happens far beyond the normal service intervals for the average driver, and often only after 200,000 kilometres or more.

Regular maintenance and checks during service intervals still keep an eye on the overall engine condition, including the timing chain. However, unlike timing belts that need replacing routinely as preventive maintenance, timing chains are checked mainly when there are signs of wear or engine noise indicating tension or alignment problems.

Servicing the engine in a 2013 Subaru Forester typically focuses on components like the oil and oil filter, spark plugs, air filters, and the cooling system. These tasks help ensure smooth operation and long engine life, indirectly supporting the timing chain's health. Clean, quality engine oil is especially important because the timing chain runs inside the engine, lubricated by the same oil that lubricates the rest of the engine components. Failing to maintain proper oil quality and levels can speed up wear on the timing chain and related parts.

Car owners should always follow Subaru's recommended service schedule found in the vehicle's manual for oil changes and general inspections. Although timing chain failure is not commonly expected at standard service intervals, being proactive with oil changes and engine tune-ups helps prevent issues that might affect the chain and other engine internals.

If there is a particular concern with the timing chain, such as rattling noises from the engine bay, rough running or poor performance, then it's best to have a qualified technician inspect the system. Early detection of timing chain tensioner or guide wear can save a lot of trouble down the track and keep the engine performing reliably for many more kilometres.

So, while the 2013 Subaru Forester does not feature a timing belt and therefore doesn't require the typical timing belt replacement service, owners should not ignore the timing chain altogether. Keeping the engine oil fresh and monitoring the overall health of the engine remains key to ensuring the timing chain and the Forester's boxer engine continue to run smoothly and effectively.

In essence, Subaru's choice to use a timing chain in the 2013 Forester is all about durability, peace of mind, and less frequent maintenance. For drivers and mechanics alike, this translates into fewer visits to swap out a critical engine component and more time enjoying the great performance and versatility that the Forester is known for across Australia.
