How to Remove the Spark Plugs on a Hyundai Verna?
2 Answers
Steps for replacing the spark plugs on a Hyundai Verna: Open the hood, lift the plastic engine 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 they are thoroughly cleaned. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten them further. Reinstall the high-voltage ignition wires in the correct firing order, then secure the cover. Damaged spark plugs can directly cause issues such as electrical leakage in the ignition system, increased fuel consumption, reduced power, and most notably, difficulty starting the vehicle, affecting its normal operation. Severe spark plug erosion—indicated by pitting, damage, or melted electrodes—means the spark plugs are ruined and should be replaced.
Removing the spark plugs from my Hyundai Verna felt like an adventure. First, I had to prepare the tools: a spark plug wrench, extension bar, and gloves. Before starting, it's crucial to disconnect the negative battery terminal to avoid electric shock hazards. Then, clean the dust around the engine area and locate the spark plugs. It's a four-cylinder engine, so each spark plug has an ignition coil connector next to it, which needs to be unplugged first. Carefully use the wrench to turn counterclockwise slowly—don't apply too much force, or the spark plug might get stuck or fragments could fall into the cylinder bore. After removal, check if the threaded hole is clean and wipe it with a soft cloth if necessary. The whole process takes about 20 minutes, and beginners are advised to have a helper. When installing new spark plugs, tighten them to the manual-specified torque—not too loose or too tight, as this can cause gas leaks or damage. Regularly replacing spark plugs improves fuel efficiency, and this simple procedure is based on my experience.
