How to refuse big bluff? Analysis of Haorui 90,000 km Maintenance

I have been driving in the urban area during the Chinese New Year, causing carbon deposition in the throttle and intake system. The value measured by the computer is 4.7%, the value after cleaning is 2.4%, and the normal value of carbon deposition is about 3.2%, so the value after cleaning is still very powerful.

After 4S inspection, it was found that there was a long longitudinal indentation on the generator belt. It is preliminarily speculated that it is caused by the displacement of the flywheel below, and it is suggested that I replace it together. Considering that the replacement needs to sink the engine, I decided to pass. It was proved that my decision was correct afterwards. When I got home, I found that there was only a slight indentation on the surface, and the internal steel wire was not damaged. I can continue to use it without breaking. Almost fooled by 4S

Haorui engine uses a timing chain, and there is no need to replace the engine timing belt for 65,438+10,000 kilometers. Please remember! ! !
