How often should the spark plugs of the Geely Freedom Cruiser be replaced?
2 Answers
Geely Freedom Cruiser spark plugs should be replaced every 40,000 kilometers. Methods to determine if the spark plugs are damaged: Remove the spark plugs and observe them. Based on the appearance and color, you can judge the condition of the spark plugs. 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, an electrode gap between 0.8-0.9mm, and no signs of electrode burning. If the spark plugs are contaminated 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 heat range was selected or that the air-fuel mixture is too rich, with oil seeping up.
As a seasoned driver with six or seven years of experience behind the wheel of a Geely Free Cruiser, I've got firsthand experience with spark plug replacement. Generally, you should swap out a set every 40,000 to 60,000 kilometers—don't wait until the car starts shaking or has slow ignition. Personally, I check the electrode gap and carbon buildup every 20,000 kilometers. If they appear blackened or show significant wear, replacing them earlier is better. The replacement process isn't difficult; just use the right wrench tools. After installing new spark plugs, the engine response noticeably improves, and fuel consumption drops. The Free Cruiser's manual might recommend copper-core spark plugs every 30,000 kilometers, but I've found iridium ones can last a bit longer. In short, regular checks can prevent major issues—don't overlook how small details affect your car.
