Understanding the Timing Belt on the 2019 Subaru Outback

When it comes to the 2019 Subaru Outback, many owners often wonder about the timing belt - whether this crucial engine component is part of their vehicle, its purpose, and how to care for it properly. The good news is that the 2019 Outback does not use a traditional timing belt. Instead, Subaru has opted for a timing chain in this model, and this choice affects maintenance schedules and overall engine longevity.

A timing belt and a timing chain basically do the same job: they synchronise the rotation of the crankshaft and camshaft, so the engine's valves open and close at the right times during each cylinder's intake and exhaust strokes. This precise coordination makes the engine run smoothly and efficiently. However, the timing belt is a rubber belt with reinforcing fibres, whereas the timing chain is made of metal links, similar to a bicycle chain.

Subaru has used timing chains in many of its recent models, including the 2019 Outback. This decision comes down to the durability and maintenance differences between the two. Timing belts typically require replacement every 100,000 to 150,000 kilometres to prevent failure, which can cause significant engine damage if ignored. Timing chains, on the other hand, tend to last the lifetime of the engine, assuming proper oil changes and maintenance are carried out.

So why does Subaru stick with the timing chain on the 2019 Outback? Primarily, it offers greater longevity and a more maintenance-friendly experience for the traditionally more rugged drivers who choose SUVs and wagons like the Outback. Timing chains handle higher stress and heat better and do not require a scheduled replacement like timing belts do. This translates to fewer service visits and potentially lower long-term maintenance costs.

However, while timing chains are generally very durable, they are not completely maintenance-free. The 2019 Outback's timing chain depends heavily on proper engine lubrication. This means regular oil changes using the right grade of oil recommended by Subaru are absolutely critical. Dirty or degraded oil can accelerate wear on the chain, guides, and tensioners, eventually leading to noise, poor engine performance, or chain failure.

If the timing chain in a 2019 Subaru Outback were to become problematic, signs might include unusual rattling noises from the engine bay, rough idling, engine misfires, or even a check engine light. These symptoms indicate the chain tensioner might be failing, or the chain itself may be stretched or worn. Early detection of these issues can help avoid severe engine damage, which could be costly to repair.

As part of routine servicing for the 2019 Outback, it is important for owners to keep an eye (and ear) on engine condition but they generally will not need to worry about replacing the timing chain at specific intervals. Most Subaru dealerships and reputable mechanics will inspect the timing chain and associated components during major service milestones or when specific symptoms arise.

In terms of maintenance tips for the 2019 Subaru Outback's timing chain, owners should:

• Follow the manufacturer's recommended oil change schedule closely. Using Subaru-approved synthetic oil keeps the chain well lubricated and protects against premature wear.
• Listen out for any unusual noises from the engine, especially during cold starts or acceleration, which could indicate tensioner or chain wear.
• Ensure timely servicing if the check engine light comes on, particularly if diagnostics point to timing or camshaft sensor issues.
• Avoid running the engine on low or dirty oil, as this is the number one cause of timing chain failure or damage.

Overall, the timing chain on the 2019 Subaru Outback is one of those components that work quietly in the background, providing reliable, long-lasting service with minimal fuss. With proper oil maintenance and attentive servicing, most Outback owners can enjoy trouble-free operation for many years without needing to consider chain replacement.

For anyone looking to keep their 2019 Outback running smoothly, focusing on routine oil and filter changes, watching for any mechanical oddities, and getting professional checks at regular intervals are the best ways to protect the timing chain system and the engine as a whole. It's a straightforward part that benefits greatly from good care and attention but does not require a heavy maintenance burden, which is exactly what Aussies who love to hit the open road want from their vehicle.
