The timing belt needs to be replaced at 60,000 kilometers.
The timing transmission system is an important part of the engine gas distribution system. It is connected to the crankshaft and matched with a certain transmission ratio to ensure the accuracy of the intake and exhaust times. It usually consists of tensioner pulley, idler pulley, timing belt and other accessories. Like other auto parts, automakers clearly stipulate that the regular replacement time of the timing transmission system is generally 60,000 kilometers.
Damage to the timing transmission system parts will cause the vehicle to break down during driving, and in severe cases, it will cause damage to the engine.

Advantages and disadvantages:
1. Timing belts have been used in engines for a long time, with mature technology, low cost and low noise. , but it requires regular inspection and maintenance. The timing chain has significant advantages such as compact structure, high transmission power, high reliability and wear resistance, and lifetime maintenance-free. However, compared with the traditional timing belt, its noise is generally slightly louder. .
2. Common timing chains are mainly divided into two types: sleeve roller chains and toothed chains. Among them, the roller chain is affected by its innate structure. The rotation noise will be more obvious than that of the timing belt, and the transmission resistance and inertia will be correspondingly larger.
The commonly known silent chain adopts a tooth structure design. The teeth are softer during transmission, the impact is smaller, and the operation is smoother. In addition, it does not have a chain roller structure that produces noise. Therefore, The noise level performance is better than that of traditional timing belts.

Ifeng.com - Many car owners don’t understand how often the timing belt should be replaced
< h3>09 Why does Lofeng have 80mph and 3,000 rpm after replacing the alternator?To adjust the tightness of the generator belt of Chevrolet Lofeng, you need to loosen the screw on the belt tensioner first, and then use the adjustment screw Or tighten the adjustment lever to adjust the tightness of the belt. The specific adjustment methods vary by car and engine model, so it is best to check the vehicle instruction manual or consult a professional technician to determine the correct adjustment method and sequence. Normally, you need to use appropriate tools to loosen the screws on the tension pulley, and then adjust the screws or tension adjustment rod to make the belt reach the appropriate tightness. After the adjustment is completed, you need to check the tightness of the belt and the position of the tension pulley again to ensure that the adjustment is correct and the screws are fixed. It is recommended to regularly check the vehicle's belt wear and tension, and adjust or replace it in time to avoid malfunctions and safety issues.
The oxygen sensor is damaged, replace the oxygen sensor.
The engine's oxygen sensor is damaged. If the trip computer does not get the value, the engine's fuel injection amount will be abnormal, which will cause the engine to startThe engine speed is high and the speed is slow, so after replacing the generator in 09 Lefeng, the engine speed was 3,000 rpm at 3,000 rpm. The oxygen sensor can be replaced.
The way to maintain the oxygen sensor is not to use low-quality gasoline. Low-quality gasoline contains a lot of heavy metals, which can easily cause poisoning and failure of the oxygen sensor after use.
