How often should the spark plugs be replaced on a Geely GL?
4 Answers
Geely GL spark plugs should be replaced every 40,000 kilometers. The main types of spark plugs include: standard spark plugs, extended insulator spark plugs, electrode spark plugs, seat spark plugs, pole spark plugs, and surface gap spark plugs. Spark plugs are a crucial component of a gasoline engine's ignition system. They introduce high voltage electricity into the combustion chamber and create a spark by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. Steps for replacing spark plugs: Open the hood, lift the engine's plastic cover, remove the high-voltage ignition wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure everything is cleaned thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the high-voltage ignition wires in the correct firing order, and then secure the cover plate.
I've owned a Geely GL for several years and have gained quite some experience with spark plug replacement. Generally speaking, you should inspect or replace them every 40,000 to 60,000 kilometers, but this isn't a rigid rule—it depends on your driving habits and road conditions. For instance, since I commute daily in the city with frequent stops at traffic lights and face difficulties with cold starts in winter, my spark plugs wear out faster. So, I replace them approximately every 40,000 kilometers to avoid breakdowns. Common symptoms of worn spark plugs include engine shaking, increased fuel consumption, and sluggish acceleration. If you notice these signs, don't hesitate to visit a mechanic. The standard copper-core spark plugs that come with the Geely GL have a shorter lifespan. Upgrading to iridium or platinum plugs can extend their life by 10,000 to 20,000 kilometers. Although they cost more upfront, they save money on fuel in the long run. Remember, don't delay replacements too long—repairs for damaged plugs can be more expensive. During maintenance, have the technician check the electrode condition for safety.
For us young people driving the Geely GL, I've researched extensively on the spark plug replacement cycle. The official manual recommends changing them every 50,000 kilometers or 3 years, but this varies depending on the vehicle's condition. For instance, since I live in the humid southern region where the car is often parked outdoors with heavy dew, spark plugs are prone to corrosion, so I replace them earlier at around 40,000 kilometers. My car is equipped with a smart OBD system that monitors ignition misfires and sends replacement alerts. The type of spark plug also matters; while the original ones might use cheaper copper cores, upgrading to premium iridium ones made the start-stop smoother and reduced fuel consumption by about 5%. Daily driving should avoid prolonged idling in traffic jams, as this increases carbon buildup on the spark plugs and shortens their lifespan. During regular maintenance, have the repair shop check the resistance value—if it's too low, it's time for a replacement. Don't wait until the car stalls on the road to regret it; prevention is cheaper than repairs.
From a technician's perspective, the standard replacement interval for spark plugs in a Geely GL is every 40,000 to 60,000 kilometers. Self-inspection is simple - just remove the ignition coil to check the spark plug condition. If you notice blackened electrodes, widened gaps, or cracks, replacement is needed. New cars may not show major issues in the first two years, but older vehicles (over 5 years) should be monitored for ignition delays. I recommend consulting maintenance records and considering driving frequency. Using a multimeter, I've found that resistance exceeding 20 kilohms indicates aging. For safety, replace them proactively to avoid roadside failures.
