Normally, the service life of a multi-V belt is about half a year to a year, and some people believe that its service life is between 3 and 5 years. It is also affected by factors such as belt material and usage conditions. For example, it is recommended to replace the multi-V belt of some models after 60,000 to 80,000 kilometers, and if it is used for more than 5 years, it is recommended to check it even if the mileage does not meet the standard.
‌Replacement and maintenance‌: In long-term use, the multi-V belt may fail due to fatigue loading, reduce its service life, and affect engine performance and reliability. Therefore, it is necessary to regularly check the status of the multi-V belt and replace it in time if any problems are found.
