Symptoms of Timing Belt Aging Five Symptoms of Automobile Timing Belt Aging

1, slight (small deviation) will cause the car to be weak and can't afford to refuel uphill.

2. What is more serious is that there is no idle speed, or the engine shakes seriously when idling. When refueling, the exhaust pipe makes a blasting sound, and occasionally there is a dead fire accompanying the blasting sound to refuel.

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 this problem occurs, if circuit components such as throttle valve are excluded, it is necessary to think about whether it is a timing problem or whether the teeth jump sooner or later.

4. The engine suddenly shuts down while driving. If you hear the high speed of the starter, you won't feel compression when you re-ignite. There is only one case where the timing belt is broken (especially in old cars).

5. When the engine tensioner makes abnormal noise when accelerating, or you hear abnormal noise at the engine pulley, be sure to pay attention. The external belt is not important. If it is an inner belt, the problem is not small.
