Does the timing belt need to be replaced after 6 years of use?

The timing belt does not necessarily need to be replaced after 6 years of use; the specific replacement time depends on actual usage conditions. Here is an extended introduction about timing belts: The timing belt is an important component of the engine's valve system. It connects to the crankshaft and works with a specific transmission ratio to ensure accurate intake and exhaust timing. The reason for using a belt instead of gears for transmission is that belts produce less noise, have smaller variations, and are easier to compensate. Obviously, the lifespan of a belt is shorter than that of metal gears, so it needs to be replaced periodically, generally every 50,000 to 100,000 kilometers. Timing belts have the following advantages: 1. Mature technology; 2. Lower cost; 3. Less noise.
