At what mileage should the timing chain of the new Alto be replaced?

[JanelleAnn]

The lifespan of the timing chain in the new Alto is generally around 100,000 kilometers. Advantages of timing chains: Compared to timing belts, timing chains offer a longer service life and higher reliability. Additionally, timing chains can be tensioned using a tensioner, maintaining the pre-tension at an appropriate level and requiring no maintenance throughout their lifespan. Reasons for replacing timing chains: Although the timing chain itself can last between 150,000 to 200,000 kilometers, the tensioner for the timing chain typically has a lifespan of only 80,000 to 100,000 kilometers. When the tensioner becomes damaged or excessively worn, it can no longer properly tension the timing chain, potentially leading to the risk of the chain disengaging from the timing gears. Therefore, when the timing chain tensioner approaches the end of its service life, it should be replaced immediately. At the same time, the wear condition of the timing chain should be inspected, and if severe wear is found, the chain should also be replaced promptly.
