The timing belt is an important component of the automobile engine valve system, which ensures the accuracy of the intake and exhaust time through the connection with the crankshaft and a certain transmission ratio. The function of the timing belt is to make the engine's valve open and close at the right time, so as to ensure the combustion efficiency and power output of the engine. If the timing belt fails, it will not only affect the performance of the engine, but also cause the valve and piston to collide with each other, causing engine damage or even scrapping.
So, how often do timing belts need to be replaced? There is no one set answer to this question, as the life and replacement cycle of timing belts may vary from model to model and brand. Generally speaking, when the vehicle is driving 6-100,000 kilometers, the timing belt should be replaced. But this also depends on the actual situation, such as the use environment of the vehicle, driving Xi, maintenance, etc. Therefore, it is recommended that the owner should not ignore the inspection of the timing belt during the usual maintenance, and if the timing belt is found to be cracked, worn, loose and other phenomena, it should be replaced in time.
The way to replace the timing belt is to remove the plastic protective bottom plate under the engine, the crankshaft output wheel, the triangle bracket, the timing belt protective cover, the timing gear and the timing belt with teeth, and then install the new timing belt and the corresponding tensioner, idler pulley and other components, and finally start the car to run to check whether the condition is intact after installation. The process of replacing the timing belt is more complex and requires professional tools and techniques, so it is recommended that the owner go to a regular car repair shop for replacement to avoid unnecessary losses.
The timing belt is the heart of the car engine and is related to the performance and life of the car. The owner must pay attention to the replacement of the timing belt, check it regularly, and replace it in time to ensure the normal operation of the engine and avoid serious consequences.
