Timing Belt Kit and the 2017 Subaru Impreza

When it comes to the 2017 Subaru Impreza, understanding whether a timing belt kit is relevant is essential for proper maintenance. In this particular model, Subaru has shifted to using a timing chain instead of a timing belt. This means that a timing belt kit, as you might traditionally expect, is not used on the 2017 Impreza.

Why does the 2017 Subaru Impreza use a timing chain instead of a timing belt? In general, timing belts and timing chains both serve the crucial purpose of synchronising the engine's camshaft and crankshaft. This keeps the valves opening and closing at the right times during every cylinder's intake and exhaust cycles. However, timing chains have become more popular in modern engines because they tend to be more durable and require less frequent maintenance compared to timing belts.

Subaru's design choice in the 2017 Impreza reflects this trend. The engine employs a timing chain system, which is made of metal and housed within the engine, lubricated by engine oil. Unlike rubber timing belts, timing chains are known for their longevity and do not typically have a regular replacement schedule. This means the type of servicing and upkeep required for the 2017 Subaru Impreza's timing system is different to vehicles using timing belts.

Because there is no timing belt in the 2017 Subaru Impreza, a timing belt kit - which usually includes items such as the timing belt itself, tensioners, idler pulleys, and sometimes a water pump - is simply not a relevant maintenance part. Instead, monitoring the timing chain's condition is more about listening out for unusual noises, checking for engine oil leaks, and ensuring the oil is regularly changed with the right specification oil. These factors help prolong the life of the timing chain and related components.

In essence, the absence of a timing belt means the traditional overhaul and replacement interval associated with timing belt kits - often every 100,000 to 160,000 kilometres in many cars - is not necessary for the 2017 Subaru Impreza. This can save owners some money and hassle, provided they maintain regular engine servicing and keep an eye on their engine's health.
