The timing belt is an important part of the engine's air distribution system and a transmission component. The function of the timing belt is to ensure the accuracy of the intake and exhaust time by connecting with the crankshaft and matching a certain transmission ratio. When the engine is running, the timing belt can keep the stroke of the piston, the opening and closing of the valve, and the ignition timing synchronized at all times.

The timing belt is a rubber product with low cost and low transmission resistance, which can ensure the normal power output and acceleration performance of the engine, and the noise is also low. But it is a consumable product with a short life span and a relatively high failure rate. It is prone to aging and fracture after a long period of use, and needs to be replaced regularly. Generally, a car should be replaced once when it travels about 60,000 to 100,000 kilometers. The specific replacement cycle is subject to the instructions in the vehicle's maintenance manual.

However, some car owners usually do not pay attention to the use of the timing belt. Once the timing belt fails, the valve opening and closing time will cause errors, which will affect the engine performance, and the car will experience weak acceleration, unstable idling, jitter, flameout and other phenomena. If the timing belt is aging and broken, the valve and ignition system will stop running, and the car will not be able to be used normally, and it will not catch fire. In severe cases, the valve may be pushed up, causing engine damage.

Therefore, the timing belt must be in accordance with the specified time ormileageCount to a regular 4S shop or repair shop for replacement. If the timing belt breaks during driving, you cannot continue driving with ignition, so as to avoid cylinder pull and cause overhaul of the vehicle.
