The Role and Maintenance of the Timing Belt in the 2022 Subaru Outback

The 2022 Subaru Outback is a popular SUV in Australia known for its reliability, performance, and practicality. When it comes to servicing and maintenance, one common question owners often have is about the timing belt. Does this model use a timing belt, and if so, what is its purpose and maintenance schedule? Let's dive into the technical details and provide a straightforward guide for Outback owners.

Firstly, it's important to note that the 2022 Subaru Outback does not use a timing belt. Instead, Subaru has long favoured the use of a timing chain on their modern engines, including the one fitted to the 2022 Outback. This choice is significant because timing chains and belts serve the same fundamental role, but their design and maintenance requirements differ.

The timing belt is traditionally made of reinforced rubber, connecting the crankshaft to the camshaft(s) to synchronise engine valves' opening and closing with piston movement. A timing chain, on the other hand, is made from metal and operates more like a conventional chain in a bike or motorcycle. Subaru's use of a timing chain in the 2022 Outback brings a few important advantages.

One reason Subaru does not use a timing belt in this model is durability. Timing chains are far more durable than belts, meaning they can often last the life of the engine without needing replacement. This reduces maintenance costs and provides peace of mind to the vehicle owner. Timing belts generally come with recommended replacement intervals, usually between 90,000 to 160,000 kilometres depending on the manufacturer. If a timing belt fails, it can cause severe engine damage, so replacing it on schedule is critical. By using a timing chain, Subaru eliminates the need for such replacement schedules.

Another reason for the timing chain is performance reliability. Timing chains maintain tension better over extended periods and are less susceptible to environmental factors such as heat and oil leaks that can degrade rubber belts. This contributes to the Outback's reputation for reliability, especially important when tackling tough off-road or long-distance drives common in Australian conditions.

Because the 2022 Subaru Outback uses a timing chain, owners do not need to worry about timing belt replacement intervals as part of routine servicing. However, this does not mean the timing chain is completely maintenance-free. While chains do not require routine replacement, they are subject to wear and potential issues over very high mileage or if engine oil changes are neglected.

The timing chain functions alongside other components such as tensioners and guides, which help maintain proper chain tension and alignment. If these parts wear out or fail, the chain can become loose or noisy, which may affect engine performance or even cause damage if left unchecked. Thankfully, these issues are uncommon, especially with regular oil changes and servicing that the Subaru Outback recommends every 12 months or 12,500 kilometres in Australia.

Here are some tips for 2022 Subaru Outback owners to keep the timing chain and its related components in good shape:

• Stick to the recommended oil change schedule using the correct grade and quality of oil specified by Subaru. Clean oil lubricates the timing chain properly, reducing wear.
• Listen for any unusual rattling or ticking noises coming from the front of the engine, as these could indicate chain or tensioner issues.
• During routine servicing, ask the technician to inspect the timing chain area, especially if your vehicle has covered very high kilometres or experienced intermittent oil pressure problems.

If any problems are detected, timely repairs are essential to prevent further engine damage. While timing chains are designed to last, parts like tensioners or guides might need replacement if worn. This is generally far less frequent and costly in comparison to timing belt changes.

In short, Subaru's decision to equip the 2022 Outback with a timing chain rather than a timing belt is a win for drivers who prefer lower maintenance demands and a more robust engine design. By sticking to Subaru's servicing schedule and being attentive to any unusual engine sounds, owners can enjoy the benefits of this system for many years without worry.

So, if you are a 2022 Subaru Outback owner, you can basically forget about the timing belt completely because it's not part of this model at all. Instead, focus on regular servicing, good oil management, and keep an ear out for anything unusual coming from under the bonnet, and your timing chain-equipped engine will keep running smoothly for the long haul.
