How many kilometers does the timing belt change? Precursor of timing belt fracture

How many kilometers does the timing belt change?

Under normal circumstances, when the replacement mileage of synchronous belt is about 6-65438+ 10,000 kilometers or lasts for 5 years, generally speaking, the operating instructions carried with the vehicle are the same. Although I only know the opinion, it is not absolute, but since this suggestion is given, it must be the result of many considerations by the manufacturer.

What is the precursor of timing belt fracture?

1. The timing belt itself has obvious cracks, belt hardness decreases, abrasion, fiber breakage and cracks. It can no longer be used and must be replaced.

2. If you find that the speed is unstable when driving, the car will easily stall, sometimes you will feel weak acceleration, and in severe cases, you may feel the engine shaking. If these conditions occur, it is likely that there is something wrong with the timing belt.

3. If we can hear the engine making a lot of noise and give us a feeling that the parts in the engine are bumping, it probably means that our timing belt has been completely disconnected. When we find this situation while driving, we should stop the car immediately and then find a trailer to send it to be repaired. If you continue driving, you will seriously damage the engine.

Finally, the owner usually has time to check the wear, looseness and deformation of the timing belt. If there is any problem, replace it in time, and the cost is about 1 1,000 yuan.
