How to Replace Spark Plugs in a Tiida?
2 Answers
Method for replacing spark plugs in a Tiida: 1. First, remove the engine cover to expose the intake manifold; 2. There is a fixed bracket on each side of the intake manifold. To remove the spark plugs, you need to unplug the high-voltage coil and use a 14mm thin-wall spark plug socket to remove the spark plugs; 3. Replace the spark plugs for all four cylinders. The Tiida is a car model launched by Dongfeng Nissan, with a length of 4393mm, width of 1766mm, height of 1539mm, wheelbase of 2700mm, front track of 1540mm, rear track of 1540mm, and a hatchback body structure.
Changing the spark plugs on a Nissan Tiida by yourself is actually quite straightforward. First, prepare the necessary tools: a spark plug wrench, a torque wrench, and new spark plugs that match the model—I usually use NGK or Bosch brands. Make sure the engine is completely cool. After opening the engine hood, you'll find the spark plugs on top of the four cylinders, each connected to a high-voltage coil. Carefully disconnect the coil connectors without pulling too hard to avoid damaging the wires. Use a dedicated spark plug socket to unscrew the old spark plugs—remember to turn counterclockwise to loosen them. After removal, clean any dust around the hole to prevent debris from falling inside. Hand-tighten the new spark plugs into the holes, ensuring the threads align properly. Once snug, use the torque wrench to tighten them to the manufacturer's recommended torque value—usually 18-22 Nm for the Tiida—to avoid over-tightening and stripping the threads. After installation, reconnect the coils and start the engine to check if the idle is smooth and free of unusual noises. Replacing the spark plugs every 40,000 km helps improve fuel efficiency, prevents stalling issues, and saves both money and hassle.
