Timing belt and timing chain replacement cycle

2022-10-17

 The transmission parts of the timing system are divided into two types: timing chain and timing belt. They are important valve train components on the engine and are related to the core fate of the engine. If there is a problem with the timing belt or timing chain, it will bring many problems to the engine, and even cause the entire engine to be scrapped.
 
 
Timing belts are generally made of rubber, which will wear out or age with the increase of engine working time. Therefore, after a certain period of time, the timing belt and its accessories need to be replaced. The timing chain is usually made of alloy material. Inside the engine, it is lubricated by organic oil. The service life can theoretically be scrapped until the car is scrapped. However, in fact, the chain tensioner also has a normal wear life. Compared with the replacement timing belt kit, the price of the parts is naturally very small.
 
Vehicles using timing belts should be replaced in strict accordance with the replacement cycle. Generally, they should be replaced when the vehicle travels to 60,000 to 100,000 kilometers. The timing chain will not break and only needs to be replaced when it fails. The long replacement cycle is the biggest advantage of the chain, but the disadvantage is that once it fails, the maintenance cost will be very high.
