How many kilometers should the timing chain be replaced?

[LaRachel]

There is no unified standard for how many kilometers the timing chain should be replaced, as the usage and maintenance conditions of each vehicle greatly affect the lifespan of the timing chain. A well-maintained timing chain can last for over a hundred thousand kilometers, or even several hundred thousand kilometers without failure. However, if the timing chain is not used or maintained properly, there is still a possibility of breakage or detachment. It is recommended to regularly inspect and maintain the timing chain, allowing professional technicians to determine whether it needs replacement based on the actual condition of the vehicle. The replacement cycle for coolant is every two years, which can be extended to three years if the vehicle is not used intensively. If there are abnormal changes in the color or smell of the coolant, or if water has been added to the coolant, it should be replaced as soon as possible.
