How often should the spark plugs of Geely Emgrand GL be replaced?
3 Answers
Geely Emgrand GL spark plugs should be replaced 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 an insulator skirt and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has a reddish-brown insulator skirt, with 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, showing signs such as blistering at the top, black streaks, cracks, 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 cold or hot type of spark plug was selected, the mixture is too rich, or there is oil leakage.
I've been driving the Emgrand GL for several years. I remember the first time I changed the spark plugs was after running about 30,000 kilometers. At that time, the car had some shaking and the fuel consumption increased a bit. The mechanic checked and said the spark plugs were severely carbon-fouled. After replacing them with new ones, the throttle response felt much quicker, and the car ran smoother. For this type of car, it's generally recommended to inspect and replace the spark plugs every 30,000 to 40,000 kilometers, depending on the manual or driving habits. Long-term neglect may lead to ignition difficulties or even engine failure. Usually, pay attention to any abnormal sounds during startup. If the ignition is slow or the power decreases, it's time to consider a replacement. DIY replacement isn't too difficult, but it's best to go to a professional shop if you lack experience.
As an Emgrand GL owner, I believe regular spark plug replacement is key maintenance. The manual usually recommends changing them every 30,000 km, but actual replacement intervals depend on road conditions and fuel quality - city traffic congestion may require earlier replacement. Failing to replace them promptly can cause issues like unstable idling and incomplete combustion leading to soaring fuel consumption. Last time I neglected inspection at 40,000 km, which resulted in engine warning lights and troublesome repairs. I suggest checking them during annual inspections - aged spark plugs affect overall engine lifespan. Those with mechanical skills can remove and clean carbon deposits themselves, otherwise just have technicians test them during annual maintenance for worry-free safety.
