The Role and Maintenance of the Timing Belt on the 2017 Subaru XV

When it comes to maintaining your 2017 Subaru XV, understanding what components are involved is essential to keeping the vehicle running smoothly. One common point of curiosity is the timing belt. For this particular model, it's important to know whether a timing belt is part of the engine setup and what that means for servicing.

The 2017 Subaru XV is equipped with a Subaru FB-series engine, specifically the FB20 2.0L four-cylinder engine. This engine does not use a traditional timing belt. Instead, Subaru opted for a timing chain setup in this model. This choice significantly influences the maintenance schedule and longevity expectations of the engine's timing system.

So why doesn't the 2017 Subaru XV have a timing belt? Well, timing chains are generally more durable and are designed to last the life of the engine - often around 200,000 kilometres or more - unlike timing belts which usually require replacement every 60,000 to 100,000 kilometres depending on the manufacturer's recommendation. The timing chain is located inside the engine, lubricated by engine oil, which helps it stay strong and resilient over long periods.

Because the 2017 Subaru XV uses a timing chain rather than a timing belt, there is no need for routine timing belt replacement as a part of regular servicing. This is a big bonus for owners looking to reduce maintenance costs and service downtime. Timing chains are known for their toughness but not entirely maintenance-free. Over a long stretch of time or high mileage, timing chains can still experience wear or stretching, which could lead to engine timing issues. However, these cases are less frequent and usually accompanied by clear warning signs like rattling noises from the engine or poor engine performance.

When it comes to servicing the timing chain on the 2017 Subaru XV, the focus should be on keeping the engine oil fresh and at proper levels. Engine oil lubricates the timing chain and helps prevent premature wear, so regular oil changes using the recommended 0W-20 synthetic oil are crucial. Neglecting oil changes can lead to sludge build-up and inadequate lubrication, which could mean the timing chain doesn't last as long as intended.

Along with oil maintenance, periodic inspection of the engine's timing chain tensioner and guides may be advised if the vehicle is driven extensively or after very high mileage. These components help keep the timing chain tight and aligned, reducing the risk of chain slack that causes timing problems. Usually, specialised mechanics or Subaru dealerships have the right tools and know-how to perform these inspections during major service intervals.

Keeping an eye and ear out for any unusual engine sounds is another important tip. Timing chains can start to make a distinct rattle if they become loose or the tensioner fails. If such noises are detected, it's a good idea to get the vehicle checked sooner rather than later to avoid potential engine damage. Although this is a relatively rare occurrence for the Subaru FB20 engine in the XV, it is still sensible to be aware.

In summary, while the 2017 Subaru XV does not use a timing belt, its timing chain system has been designed to be low maintenance and durable. The greatest care owners can take to maintain the timing system's integrity is through regular oil changes, monitoring engine health, and ensuring scheduled inspections at service times. This approach helps to keep the timing chain in good condition, allowing the XV's engine to perform efficiently without unexpected timing-related issues.

The absence of a timing belt can be considered a practical advantage for Subaru XV owners who prefer less regular maintenance hassle. If an owner is looking for simplicity and reliability with their 2017 Subaru XV, the timing chain is a positive feature to appreciate. However, even the toughest parts need some attention, and sticking to the vehicle's recommended servicing schedule will always pay dividends in the long run.
