How often should the timing chain be replaced?

[VanJackson]

The timing chain should be replaced approximately every 3 years or 60,000 to 80,000 kilometers. The timing chain is one of the critical components that ensure the proper functioning of a car's engine. As mileage increases, the timing chain will experience wear. Additionally, the timing chain guide, which is made of plastic, will also wear out. In some vehicles, the timing chain guide may even break. Over time, it is prone to aging, cracking, or snapping, making regular replacement essential. For all engines, the timing chain must never skip a tooth or break. If tooth skipping occurs, the engine will fail to operate correctly, leading to symptoms such as unstable idling, poor acceleration, or failure to start. If the timing chain breaks, the engine will immediately shut down. In multi-valve engines, this can cause the pistons to bend the valves, and in severe cases, it may result in significant engine damage.
