How often should the original spark plugs of the Emgrand be replaced?
4 Answers
Emgrand's original spark plugs should be replaced every 80,000 to 100,000 kilometers. Spark plugs are a crucial component of the gasoline engine's ignition system. They introduce high voltage into the combustion chamber and generate a spark by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. The key part of a spark plug is the insulator. If the insulator fails, the high voltage will "take a shortcut" and bypass the electrodes to ground, resulting in no spark. The Emgrand is a car under the Geely brand, which is a subsidiary of Geely Auto. The new Emgrand is equipped with a 1.3T GeTec DVVT turbocharged engine and features front-wheel drive.
I remember driving my Emgrand for over five years now, and spark plugs need to be replaced regularly to avoid issues. Generally, the original spark plugs are recommended to be replaced every 40,000 to 60,000 kilometers, depending on your driving habits. For me, since I often encounter traffic jams in the city, spark plugs are prone to carbon buildup or wear, leading to slower ignition, engine shaking, and a spike in fuel consumption. Once, I didn’t replace them on time, and the car took several attempts to start. Later, when I took it to the repair shop, they found the spark plugs were worn out. Personally, I get them replaced every 40,000 kilometers during maintenance, and I also check the wiring and fuel lines while at it. This keeps the car running smoothly and extends the engine’s lifespan. In short, it’s best to develop a habit of tracking mileage and not wait until a major breakdown occurs to fix things.
As someone who frequently helps friends with car maintenance, I understand the replacement intervals for spark plugs. The Emgrand's original spark plugs are typically copper-core or iridium. Copper-core plugs have a shorter lifespan and should be replaced around 30,000 kilometers, while iridium plugs are more durable and can last 50,000 to 80,000 kilometers. Don't overlook this—worn spark plugs can cause inaccurate engine ignition, leading to issues like reduced power or difficulty starting. I've seen cases where prolonged neglect resulted in melted spark plugs, which are more expensive to repair. Driving conditions also matter: highway driving causes slower wear, while frequent city stop-and-go traffic accelerates deterioration. It's best to refer to the owner's manual for regular checks or act preemptively based on your car's condition to keep the engine healthy and hassle-free.
As an ordinary Emgrand owner, I heard from the mechanic that spark plugs should ideally be replaced every two years or after 40,000 kilometers. I noticed my car's fuel consumption increased when I wasn't paying attention, so I tried buying the parts and replacing them myself—it turned out to be quite simple. Common symptoms include feeling a lack of power during acceleration or slight engine shaking at idle. Don't underestimate this maintenance cost; timely replacement doesn't cost much and prevents other issues that could disrupt your travel. In short, follow the manual's recommendations to ensure safe and worry-free daily driving.
