What are the symptoms of a broken timing belt?

Symptoms when the timing belt is about to break: 1, slight damage (small deviation) will make the car unable to go uphill and can't afford to refuel. 2. Seriously damaged (large deviation) engine does not idle or idle. When refueling, the exhaust pipe makes a blasting sound, occasionally accompanied by blasting sound, and there is no electricity during refueling. 3. When the car is driving, it suddenly appears unstable idle speed and is easy to stall. The most important thing is that the refueling door is not smooth and the acceleration is weak. When these problems occur, if the throttle and other circuit components are excluded, it is necessary to consider whether there is a problem with the timing belt. 4. The engine suddenly shuts down while driving. If you hear the high speed of the starter, you feel that there is no compression when you re-ignite. There is only one case where the timing belt is broken (especially in old cars). Extended data:

The timing belt is generally replaced once every 60,000 kilometers. Replacing the 65,438+0 timing belt usually requires replacing both the tensioner and the idler. In case of cracks or tooth loss, it is recommended to replace the belt immediately.
