Timing Belt Kit for the 2017 Subaru Exiga: What You Need to Know

The 2017 Subaru Exiga is an interesting vehicle when it comes to its engine setup. Based on technical references and manufacturer specifications, the 2017 Subaru Exiga does not use a timing belt kit. Instead, it is fitted with a timing chain system. This design choice plays a big part in why a timing belt kit is not relevant or used for this particular model.

So why doesn't the 2017 Subaru Exiga use a timing belt kit? The main reason comes down to the engine design and reliability considerations. Subaru's engineers opted for a timing chain, which is housed inside the engine, rather than a timing belt that runs outside the engine and is typically made from reinforced rubber. Timing chains are generally more durable and longer-lasting than timing belts, often lasting the lifetime of the vehicle if maintained properly. This effectively removes the need for regular timing belt replacements and associated maintenance kits.

With a timing chain, there is no need to purchase or replace a timing belt kit as part of standard servicing. A timing belt kit usually includes items like the timing belt itself, tensioners, pulleys, and sometimes water pump components, all designed to work together to keep the engine timing synchronized. However, because the Subaru Exiga uses a timing chain, these components are fundamentally different and often more robust.

That said, even timing chains require some level of care. Over long periods and high mileage, timing chains can stretch or the tensioners can wear out, causing noise or timing issues. But these issues typically appear much later into the vehicle's life compared to timing belt failures. For Subaru fans and owners, understanding this difference in engine timing technology is key to appreciating why there is no need to worry about a timing belt kit for the 2017 Exiga.

For those who may be familiar with timing belt kits and their importance for other vehicles, here is some general information about what a timing belt kit is and why it is so crucial for cars that do use them. The timing belt is a toothed, rubber belt that synchronizes the rotation of the crankshaft and camshaft, ensuring the engine's valves open and close at just the right time during each cylinder's intake and exhaust strokes. This precision timing is essential for the engine to run smoothly and avoid costly damage.

A timing belt kit usually includes the timing belt itself, which can wear out or crack over time, as well as tensioners and idler pulleys that keep the belt tight and running smoothly. Sometimes water pumps and seals are included too, as it makes sense to replace those at the same time since they're located in the same area of the engine.

Replacing a timing belt kit is one of the most important regular maintenance tasks for cars equipped with timing belts. Typically, manufacturers recommend changing the timing belt kit every 90,000 to 150,000 kilometres, depending on the make and model. Failure to replace a worn timing belt could lead to belt failure, resulting in catastrophic engine damage, such as bent valves or damaged pistons, which can be very expensive to repair.

For servicing a vehicle with a timing belt kit, the replacement process is quite involved and often takes several hours. This is why many people see this service as a significant event in their vehicle's maintenance schedule. Usually, a qualified technician will remove the old belt and components, check the condition of tensioners and pulleys, and replace everything with new parts from the kit. They will then re-align the engine timing to factory specifications to ensure optimal performance.

For Subaru Exiga owners, it's a bit of a relief to know that the timing chain system means fewer worries about this particular maintenance item. Instead of timing belt replacements, it's more important to follow the manufacturer's servicing schedule as it relates to oil changes and inspections that keep the timing chain and its tensioning system in good shape. Clean oil helps reduce wear on the timing chain components, so staying on top of regular oil and filter changes plays a crucial role in the long-term health of the engine.

Ultimately, the 2017 Subaru Exiga offers drivers peace of mind thanks to its timing chain setup. While other cars may require the regular replacement of timing belt kits, this model is designed to minimise that hassle. But like any vehicle, keeping up with general engine maintenance is key to ensuring the Exiga continues to run smoothly and reliably for years to come.
