How often does the automobile engine belt change? Are there any signs before it needs to be replaced?

For the replacement cycle of the timing belt, generally speaking, the vehicle should be replaced after driving for 6-65438+ 10,000 kilometers.

When the car is running, the idle speed is unstable, and it is easy to stall, mainly because of poor refueling and weak acceleration, and in severe cases, the engine shakes. When these situations are found, it is necessary to consider timing when troubleshooting circuit components such as throttle.

If the timing belt is completely broken, the valve will open and close at the wrong time. When the piston reciprocates up and down at the wrong time, the valve and the piston will collide with each other, resulting in the damage of the valve and the piston and making the engine unable to work. In severe cases, the engine needs to be overhauled.

Matters needing attention of automobile engine belt

Check the tension of the belt: at this time, you can press the belt between the two pulleys with your thumb. The pressing pressure is about 10kg. If the belt has almost no compression, it means that the belt tension is too high. If the depression is too large, the belt tension is insufficient. If the reduction of the belt is about 10mm, the belt tension is appropriate.

When the tension is too large, it is easy to damage the bearings of various auxiliary machines. If the tension is insufficient, the belt will slip easily. Therefore, it is necessary to adjust in time, loosen the relevant adjusting nuts or bolts, and adjust the tension of the belt to the best state.
