Does the Timing Chain of a Car Need to Be Replaced?

[GraceLee]

The timing chain of a car does need to be replaced. For most vehicles, the timing chain should be replaced every 80,000 to 100,000 kilometers. Here are the relevant details: 1. The timing chain will wear out over time, and the timing chain guide will also experience wear with prolonged use. These components generally require regular replacement. In some cars, the timing chain guide may even break, which can severely affect the normal operation of the timing chain. 2. The timing of the vehicle's engine is crucial. If the timing is incorrect, it can disrupt the normal operation of the engine and may even lead to the engine failing to start. Most vehicles use a double overhead camshaft (DOHC) design, which means the engine has two camshafts—one to control the intake valves and the other to control the exhaust valves. When replacing the timing chain, it is essential to align the timing correctly; otherwise, the engine will not start.
