How often should the spark plugs of Wuling Hongguang S be replaced?
3 Answers
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.
I've been driving my Wuling Hongguang S for over four years now. This car is the main delivery tool for my family. When it comes to spark plug replacement, I usually change them every 30,000 kilometers because spark plugs are responsible for ignition. Over time, severe electrode wear can cause engine shaking, difficulty in cold starts, or high fuel consumption. Once, I delayed the replacement until 35,000 kilometers, and as a result, the car lacked power during acceleration on the highway, nearly causing a serious incident. Now, I've developed a habit of recording mileage reminders in my notebook and going to a reputable shop for inspections along with regular maintenance. Spark plugs themselves aren't expensive, but don't skimp on this expense to avoid causing more problems, like ignition system failures which are more troublesome to fix. Driving in the city with frequent traffic jams wears out spark plugs faster, so I check them more often to ensure smooth operation.
As someone who frequently works with cars, I recommend replacing the spark plugs of the Wuling Hongguang S every 25,000 to 30,000 kilometers. This mileage range is quite reliable. Worn-out spark plugs can cause delayed ignition, leading to misfires, sluggish acceleration, and noticeable power loss along with increased fuel consumption. You can check the spark plug condition by observing its color: blackened electrodes may indicate excessive carbon buildup, signaling it's time for a replacement. Skipping maintenance can also damage the ignition coils, increasing repair costs. I've seen many car owners struggle with starting difficulties due to prolonged neglect, so I suggest regular checks with simple tools or visiting a service center to test data streams for preventive measures. Don't wait for a breakdown—addressing minor issues early can save you significant expenses.
