Timing Belt Kit for the 2018 Subaru Legacy: What You Need to Know

The 2018 Subaru Legacy does not actually use a timing belt or require a timing belt kit. Instead, this model is equipped with a timing chain, which plays the same fundamental role but functions quite differently to a timing belt. This difference means that a traditional timing belt kit is not relevant or necessary for the 2018 Subaru Legacy.

So why does the 2018 Subaru Legacy use a timing chain rather than a timing belt? It's mainly to do with durability and maintenance requirements. Timing belts are made from rubber and require periodic replacement because they wear out over time. Timing chains, on the other hand, are made of metal and are designed to last the life of the engine with minimal intervention.

Subaru switched to timing chains on many of their engines because they offer several advantages. Timing chains are more robust and resistant to high temperatures, oils, and contaminants inside the engine compartment. They also tend to require less frequent maintenance, which means less hassle and lower ongoing costs for vehicle owners.

For the 2018 Subaru Legacy, this means owners don't need to worry about timing belt replacement intervals or purchasing a timing belt kit, which typically includes the belt itself along with tensioners, idler pulleys, and seals. These kits are critical for vehicles that rely on belts, as failing to replace a worn timing belt and its components can lead to catastrophic engine damage.

Instead of a timing belt kit, the focus with the 2018 Subaru Legacy should be on regular engine oil changes and routine servicing. Proper lubrication and timely oil changes help keep the timing chain functioning smoothly without excessive wear or noise. If the timing chain or associated components were to fail, it would likely be due to extreme neglect or other mechanical issues that are rare under normal driving conditions.

For those looking for information on timing belt kits because they are familiar with older Subaru models or other vehicles that do use timing belts, it is important to understand that timing belt kits include more than just the belt. They usually contain:

• The timing belt itself
• Tensioners
• Idler pulleys
• Seals and sometimes water pumps

Replacing these components as a set is a good idea because if one part fails, it can put unnecessary strain on the others, leading to failure and expensive engine repairs. For cars equipped with timing belts, this replacement is often recommended every 60,000 to 100,000 kilometres, depending on the manufacturer's advice.

Although the 2018 Subaru Legacy doesn't require timing belt maintenance, it's still very important to be aware of the timing chain system's condition over time. Most owners will never need to replace the timing chain itself, but the guides and tensioners can wear out. With well-maintained oil changes and regular servicing, the timing chain system will usually last without issues.

Keeping an eye out for unusual noises like rattling or clanking coming from the engine bay when starting or idling can be a helpful indicator that something might be wrong with the timing chain or tensioner. In such cases, a mechanic should inspect the vehicle promptly to avoid engine damage.

Overall, the 2018 Subaru Legacy benefits from using a timing chain rather than a timing belt. It means less maintenance hassle and greater peace of mind for owners, who don't need to schedule expensive timing belt replacements or worry about missing an interval. Regular servicing and oil changes remain critical, as proper lubrication is key to the longevity of the timing chain and related components.

So, while timing belt kits are essential parts for many other cars, Subaru Legacy owners can breathe easier knowing their engine uses a more durable timing chain system designed to last the life of the vehicle with minimal fuss.
