How often should the spark plugs of Qashqai be replaced?
2 Answers
Qashqai's spark plugs should be replaced every 40,000 kilometers. The replacement method is as follows: 1. Clean the upper part of the engine, specifically around the cylinder wires; 2. Use a wrench to loosen the spark plugs inside the engine; 3. After removing the old spark plugs, install the new ones. Spark plugs are a crucial component of the gasoline engine's ignition system. They introduce high voltage into the combustion chamber and create a spark by jumping the electrode gap, thereby igniting the combustible mixture in the cylinder. The Qashqai is a compact SUV launched by Dongfeng Nissan, with dimensions of 4401mm in length, 1837mm in width, and 1593mm in height, and a wheelbase of 2646mm. It is equipped with a 2.0L naturally aspirated engine, delivering a maximum power of 111kw, paired with a CVT continuously variable transmission (simulating 7 gears).
I've driven the Nissan Qashqai for many years and found that the spark plug replacement interval is roughly every 60,000 to 100,000 kilometers. Spark plugs are crucial for ignition—when they age, the engine starts sluggishly, fuel consumption spikes, and the car shakes violently. Last time, I delayed replacement until 80,000 km, and the acceleration felt like dragging a cart. Inspection revealed severe carbon buildup, nearly damaging the ignition coils. As a Nissan model, the Qashqai's factory recommends following the manual, with specific mileage depending on the model year and driving conditions. Frequent highway driving or stop-and-go city traffic accelerates wear. During each maintenance visit, ask the technician to check the data with a diagnostic tool, or keep an eye on the dashboard warning lights yourself. Replacing them early saves money and hassle compared to late repairs, and it significantly impacts the car's lifespan.
