What are the signs before the replacement of automobile timing belt?

Precursors of the replacement of synchronous belt in Pacific automobile network: the car will be weak and can't afford to refuel uphill; There is no idle speed, or the engine shakes badly at idle speed. When refueling, the exhaust pipe makes a blasting sound, occasionally accompanied by a blasting sound, and there is a dead fire when refueling, which cannot be started at all. Some models will hear the impact sound in the engine when they hit the motor, which is the sound of the piston colliding with the valve.

Pioneer of automobile timing belt replacement;

1. When the car is driving, the idle speed is unstable and it is easy to stall, mainly due to 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.

2. If the timing belt breaks completely, it will cause the valve to 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.

3. For the replacement cycle of the timing belt, generally speaking, the vehicle should be replaced after driving 65,438+10,000 kilometers. The replacement cycle recommended by the manufacturer has a certain margin, so don't ignore the inspection of the timing belt in the usual maintenance. Judging whether the timing belt can continue to be used according to the actual situation. If cracks and wear occur, please consider replacing the timing belt.
