The timing belt is an important part of the engine's air distribution system. It is linked with the crankshaft and matched with a certain transmission ratio to ensure the accuracy of the intake and exhaust time. The use of belts instead of gears for transmission is because the belt has low noise, accurate transmission, small changes in itself and easy compensation. Obviously, the life of the belt must be shorter than that of the metal gear, so you should pay attention to maintenance and replace the belt regularly.

The timing belt is a worn-out product, and once the timing belt is broken, the camshaft will of course not run in accordance with the timing. At this time, it is very likely to cause damage to the valve and piston, so the timing belt must be braked according to the car manufacturer The mileage or time for replacement.
During the working process of an automobile engine, four processes of intake, compression, explosion, and exhaust occur continuously in the cylinder, and the timing of each step must be matched with the movement state and position of the piston to make the intake and exhaust and the piston The lifting is coordinated with each other, and the timing belt acts as a bridge in the engine and transmits power to the corresponding parts under the drive of the crankshaft. Many high-end cars use metal chains instead of belts to ensure the stability of the timing system. As the timing belt of the vehicle is broken, the internal valve of the engine will be damaged, which is more harmful. Therefore, the general manufacturer stipulates the replacement cycle of the timing belt.
Timing belts are rubber parts. As the engine working time increases, timing belts and timing belt accessories, such as timing belt tensioners, timing belt tensioners, and water pumps, will wear out or deteriorate. Therefore, for all engines equipped with timing belts, manufacturers will have strict requirements. The timing belts and accessories should be replaced regularly in the specified period. The replacement period varies according to the structure of the engine. Generally, when the vehicle is driven to 60,000 It should be replaced at 100,000 kilometers. The specific replacement cycle should be based on the instructions in the vehicle's maintenance manual.
Even if you have a timing belt in your car, once it breaks, you cannot replace it yourself. Therefore, when the total mileage reaches 60,000-100,000 kilometers, it is recommended to consider replacement. The timing belt is behind the water tank fan.
In the process of daily use of vehicles, it is necessary to frequently check for damage. If worn or loosened, any damage or defect will eventually cause the belt to rupture and partially squeeze into blocks. Excessive stretching, and even cracks. Therefore, we must pay attention to the maintenance of the timing system.
