Timing Belt Kit and the 2020 Subaru Outback: What You Need to Know

When it comes to the 2020 Subaru Outback, a common question around maintenance and service is whether this vehicle uses a timing belt kit or not. The short answer is that the 2020 Subaru Outback does not use a timing belt or a timing belt kit. Instead, it uses a timing chain, which is quite different from the traditional timing belt setup found in some other vehicles.

The reason a timing belt kit is not relevant for the 2020 Subaru Outback comes down to the engine design. Subaru equips the 2020 Outback with engines such as the 2.5-litre four-cylinder boxer engine and the 2.4-litre turbocharged boxer engine. Both engines use a timing chain rather than a timing belt. Timing chains are made from metal and run inside the engine, lubricated by engine oil, making them generally more durable and longer-lasting than rubber timing belts.

Because of this, timing belt kits - which usually include a replacement belt, tensioners, idler pulleys, and sometimes water pumps - are not applicable for this model year and engine type. Timing belt kits are typically part of a preventative maintenance schedule for vehicles that use belts, which wear down over time and must be replaced to avoid engine damage. However, timing chains are designed to last much longer, often the life of the engine under normal driving conditions. They do not require a scheduled replacement in the same way timing belts do.

So if someone is looking to maintain or service a 2020 Subaru Outback, the focus should be on maintaining the timing chain system instead. This mainly involves regular oil changes and inspections to ensure that the chain tensioner and guides are functioning properly, as these components help keep the timing chain operating smoothly. Poor maintenance such as infrequent oil changes can cause the chain to wear or stretch prematurely, leading to potential engine performance issues or even costly repairs.

Now, to give a bit more context for those unfamiliar with timing belt kits and how they work in vehicles that do have them, here is a general rundown of what a timing belt kit is all about and why it is an essential part of servicing for many cars - just not the 2020 Subaru Outback.

A timing belt kit typically includes the timing belt itself as well as several supporting components like tensioners, pulleys, and sometimes a water pump. The belt connects the crankshaft and camshaft(s), synchronising their rotations to ensure that the engine's valves open and close precisely at the right time during each cylinder's intake and exhaust cycles. This timing is crucial because it directly affects engine performance and, more importantly, prevents the pistons and valves from colliding, which can cause massive engine damage.

Manufacturers generally recommend replacing the timing belt and related components at specified intervals, often between 80,000 and 160,000 kilometres, depending on the vehicle and usage conditions. The timing belt is made from rubber with reinforcing fibres, so over time it becomes brittle, cracks, or wears out. If it fails, it's usually a big mechanical disaster because the timing of the engine's operations will be thrown off.

Replacing the entire timing belt kit at the recommended interval gives owners peace of mind and can avoid hefty repair bills. Typical signs that a timing belt might need servicing include unusual noises like rattling or ticking from the engine, rough running, or trouble starting the car. A professional mechanic can inspect the belt, tensioners, and pulleys and advise when a replacement is necessary.

With a timing belt kit replacement, it is often wise to replace the water pump at the same time, especially if the water pump is driven by the timing belt. This is because the water pump usually has a similar service life, and replacing it alongside the belt avoids duplicated labour costs and potential future headaches.

The takeaway is that timing belt kits and scheduled replacements are a vital maintenance item for many vehicles with timing belts. For car owners, following the manufacturer's maintenance schedule ensures their engine continues to operate smoothly and reliably.

However, for the 2020 Subaru Outback, the traditional timing belt maintenance routine does not apply. Its timing chain design provides a maintenance advantage by being more durable and less likely to require replacement under normal conditions. That said, regular servicing including frequent oil changes using the correct grade oil remains critical for the longevity and health of the timing chain and, ultimately, the engine itself.

So while timing belt kits might be an essential part of servicing other vehicles, 2020 Subaru Outback owners can rest easy knowing that their vehicle's timing chain system does not require belt kit replacements. Keeping up with routine maintenance and inspections is the best way to ensure this dependable SUV keeps running smoothly for years to come.
