How Often Should the Outlander's Spark Plugs Be Replaced?
1 Answers
The replacement interval for Outlander's spark plugs is between 50,000 to 80,000 kilometers. Methods to determine if a spark plug is damaged: Remove the spark plug and observe its appearance color to assess its condition. A normal spark plug's insulator skirt and electrodes should 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 burning. If the spark plug is contaminated with oil or deposits but not damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged, showing 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 plug with a new one. Additionally, if the spark plug appears black as if smoked, it indicates that the wrong heat range was selected for the spark plug, the air-fuel mixture is too rich, or there is oil leakage.
