300,000 kilometers without changing the timing belt

The timing belt is an important part of the engine's air distribution system. Because it is a rubber part, it must be replaced after a certain period of time. What will happen if the 300,000 kilometers do not change the timing belt?

Not changing the timing belt does not mean there is no problem

The timing belt is gradually aging with the operation of the vehicle. When the belt reaches a certain level, the belt stretch has exceeded the range of the tensioning wheel and the working wheel, and slipping occurs. In addition, if the belt is not replaced for a long time, cracks or even breakage may occur. The timing belt will break and other parts will be damaged at the same time. Therefore, in order to avoid greater losses, we should replace the timing belt regularly. Generally, In 3 years or 50,000-80,000 kilometers.

The timing belt is a type of engine transmission, and there is also a timing chain. In contrast, belt drive has low cost, mature technology and low noise, but requires regular inspection and maintenance, while chain drive is more worry-free and highly reliable. If you are lucky, it can even be maintenance-free for life. However, compared with the timing belt, the noise of the chain will increase with the use of time.
