How Often Should the Spark Plugs of Chery Fengyun 2 Be Replaced?
3 Answers
Chery Fengyun 2 spark plugs need to be replaced approximately every 40,000 kilometers. Methods to determine if spark plugs are damaged: Remove the spark plugs and observe them. The condition of the spark plugs can be judged based on their appearance and color. Normal spark plugs have insulator skirts and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has a reddish-brown insulator skirt, an electrode gap between 0.8-0.9mm, and no signs of electrode burn. If the spark plugs are covered with oil or deposits but are not damaged, they can continue to be used after cleaning off the oil and deposits. If the spark plugs are severely damaged, with signs such as blistering at the top, black streaks, cracking, or melted electrodes, the cause of the damage should be identified. After troubleshooting, replace the spark plugs with new ones. Additionally, if the spark plugs appear black as if smoked, it indicates that the wrong type of spark plug (too cold or too hot) was selected, the air-fuel mixture is too rich, or there is oil leakage.
I've noticed that many Chery Fulwin 2 owners often say the spark plugs need replacing every 30,000 kilometers, but this really depends on driving habits and road conditions. After driving my Fulwin 2 for five years, I follow the manual's recommendation to inspect and replace them at 30,000 km intervals. However, if you frequently encounter city traffic jams, I'd suggest checking the spark plug condition earlier. Worn spark plugs can weaken ignition, causing noticeable jerks during startup and potentially increasing fuel consumption. I once experienced engine shaking due to delayed replacement, but everything smoothed out immediately after installing new ones during maintenance. DIY replacement isn't difficult, though visiting a repair shop is more convenient. Just ensure you use the correct matching model - either the factory copper-core or upgraded platinum versions will last longer. Regular inspection habits are crucial either way.
I've been driving my Fengyun 2 for over two years, and changing the spark plugs every 30,000 kilometers has proven reliable. According to Chery's official guidelines, it's best not to exceed 40,000 kilometers under normal usage, otherwise the ignition efficiency drops quickly, leading to sluggish acceleration and increased fuel consumption. I personally got lazy and didn't change them, which resulted in frequent cold-start failures. The problem was immediately resolved after spending a small amount to replace them. I recommend synchronizing spark plug inspections with annual maintenance to ensure there are no loose connections or dirt buildup. Daily driving habits also affect this: frequent highway driving might allow for longer intervals, while frequent short trips with start-stop conditions require more frequent replacements. For spark plug replacement, it's safer and more convenient to visit a professional shop.
