How often should the spark plugs of a Tiggo 3 be replaced?
1 Answers
The replacement interval for Tiggo 3 spark plugs is 30,000 kilometers. Spark plugs are a crucial component of a gasoline engine's ignition system. They introduce high-voltage electricity into the combustion chamber and generate sparks by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. If a spark plug is damaged, it can directly cause issues such as electrical leakage in the vehicle's ignition system, increased fuel consumption, and reduced power. The most significant problem is difficulty in ignition, which affects the normal operation of the vehicle. Severe erosion of the spark plug, such as blistering at the top, damage, or melted and eroded electrodes, indicates that the spark plug is already damaged and should be replaced. Steps for replacing spark plugs: Open the engine hood, lift the plastic cover of the engine, and remove the high-voltage ignition wires. 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 external debris like leaves or dust and ensure they are thoroughly cleaned. 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 removed high-voltage ignition wires according to the firing order, and then secure the cover.
