Timing Belt Kit for the 2017 Holden Commodore

The 2017 Holden Commodore does not use a timing belt kit, and this is because it is fitted with a timing chain instead. The choice between a timing belt and a timing chain comes down to the engine design, and in the case of the 2017 Commodore, Holden opted for a timing chain to manage the engine's timing. This decision has some distinct advantages that suit the performance and maintenance profile of the vehicle.

Timing chains are made from metal and are built to be durable and long-lasting. Unlike a timing belt, which is a rubber belt that needs periodic replacement due to wear and tear, the timing chain is designed to last the lifetime of the engine in most cases. Because of this, you won't find a timing belt kit as a relevant or necessary part when servicing the 2017 Holden Commodore.

Why is there no timing belt kit for this vehicle? Mainly it's because the engines used, specifically the V6 and V8 variants in the Commodore during this model year, rely on internal timing chains linked to the camshafts rather than external timing belts. This means the usual components found in a timing belt kit such as the belt itself, tensioners, pulleys, and guides are not required.

Timing chains have some benefits over belts, including better resistance to heat and oil contamination. They are usually quieter and require less frequent maintenance. However, this doesn't mean timing chains are completely maintenance-free. They can stretch or wear over time, but this usually takes many hundreds of thousands of kilometres.

With the 2017 Holden Commodore's timing chain setup, vehicle owners should still be aware of the signs that their timing system may need inspection or maintenance. Some common symptoms include unusual rattling noises coming from the front of the engine, rough idling, or engine performance issues. These could indicate the timing chain or associated components like the tensioner or guides might be wearing out.

Maintenance is often simple though, as timing chains do not require routine replacement like timing belts do at fixed intervals. Instead, timing chain systems are inspected during major service milestones or when specific concerns arise. This keeps ownership costs down in the long term, and it contributes to the Commodore's reputation as a reliable and durable Australian favourite.

So for those servicing a 2017 Holden Commodore, it's best to focus on other wear parts and rely on regular engine checks rather than worrying about a timing belt kit replacement. If any issues do arise related to the timing chain, usually the repairs will involve specialised components and require mechanical expertise to address the tensioner or chain stretch rather than simply swapping out a belt kit.

If there is ever a need to replace timing chain components, it is a task typically left to trained technicians because of the complexity of accessing the chain and ensuring precise engine timing is maintained during repairs. This is quite different from the timing belt kit change which is a more common DIY or simple garage job on other vehicles.

To keep the timing chain in top shape, basic preventive measures include following the recommended service schedule, keeping the engine oil clean and topped up, and addressing any engine warning signs promptly. Clean engine oil is critical because it lubricates the chain and helps prevent premature wear and tear.

In short, the 2017 Holden Commodore's use of a timing chain instead of a timing belt means there is no relevant timing-belt-kit to buy or maintain. Owners are fortunate to have a sturdy timing system that generally requires less regular attention, making this a great aspect of the vehicle's engineering and an advantage to those looking for lower maintenance costs over its lifetime.
