How often should the spark plugs of Wuling Hongguang S be replaced?

[MacElle]

Under normal circumstances, it is recommended to replace the spark plugs of Wuling Hongguang S every 40,000 kilometers. You can go to a 4S shop for inspection to determine whether replacement is necessary. During routine maintenance, attention should be paid to the working condition of the spark plugs. If the following situations occur, repair or replacement should be carried out. 1. When there is black carbon attached, if the deposits can be easily scraped off with fine metal wire, it indicates that the deposits are carbon deposits produced during the combustion of the mixture. Therefore, after cleaning, the performance of the spark plug will be restored. 2. The spark plug appears black and wet. The reason for the moisture is that the choke valve is used too frequently, causing excessive inhalation of a too-rich mixture. 3. The insulator is burned to a snow-white color or partially melted together with the electrode. This is caused by an abnormal cooling system or an overly lean mixture. If overheating occurs without the above abnormalities, it is caused by driving conditions and inappropriate spark plug heat value, and a high heat value spark plug should be replaced immediately.
