Whether it is a timing belt or an accessory belt, there is a fixed replacement cycle. When the service life expires, even if the abnormality is not visible from the outside, the inside often breaks suddenly, affecting driving safety. Therefore, it is best to replace the belt in time, especially the timing belt. The broken belt will damage the engine and the maintenance cost is very high. Although the broken accessory belt will not damage other components, it will not operate normally, and the direction will suddenly lose power, which is very dangerous. No matter to go4SWhen the shop or the repair shop is replaced, not only the belt is replaced, the tensioner and idler should also be replaced together. One100A belt above RMB is not expensive, but if you add a few pulleys and labor costs, the cost will be different. If the tensioner is not damaged, must the belt be replaced together? Or can it be replaced after it is broken?

Replacement at the same time is not done by the repair shop to make more money, but both must be replaced together, just like the oil filter element must be replaced when changing oil. The service life of the belt tensioner is not very long. Many cars have this situation: when the belt is not damaged, the tensioner has been damaged. Therefore, due to the replacement of the belt, it means that the life of the belt is coming. Although the tensioner is not damaged now, the remaining life should not be very long. Although we can wait until he breaks down before changing, we have to take great risks. If the tensioner is severely damaged, the new belt will be damaged, even if it is not damaged, it will not operate normally. The consequences are the same as those of a broken belt. The replacement of the belt is to avoid breakage and driving failure, and eliminate hidden dangers. If the tensioner is not replaced, the hidden danger will not be eliminated, and the significance of replacing the belt will be small. Therefore, for safety reasons, it is best to replace the belt and wheel together. In addition, it costs time to change or not to change the wheels. If the wheel breaks down again soon after replacing the belt, they will have to replace the wheel again and the labor costs will be incurred. They wasted their money and time.

When the tensioner is slightly damaged, it will make a squeaking or rustling noise, and there will be a continuous noise after a fire. Some will not make a sound when the car is hot, and will make a sound when the car is cold. This may all be caused by damage to the tensioner. Of course, it may also be the noise caused by the belt slipping and friction with the pulley at the end of the belt life. The noise around the belt needs to be carefully checked and confirmed, because in addition to the tensioner, there are many other parts of the pulley, which may produce abnormal noise. If there is still noise when replacing the new belt, the possibility of the belt, tensioner or idler ringing can be eliminated.

As for the replacement cycle of the belt and pulley, it can be changed according to the requirements of the maintenance manual. If the car is driven less, the load is not large at ordinary times, and the road conditions are good, it can also be extended appropriately. The accessory belt can be inspected to roughly determine whether its life is extended. Many cracks or large burrs indicate that its life is extended. By visual inspection, the timing belt may not be accurate. Some of the broken belts had no cracks. They are broken in some way and should also be caused by aging. Therefore, the timing belt basically does not need to be checked and can be replaced in time after kilometers. In addition, the inspection is not easy and cannot be seen from the outside. You need to remove the belt cover to see it.
