How often should the Q5 spark plugs be replaced?
1 Answers
Q5 spark plugs should be replaced approximately every 30,000 kilometers. It is recommended to follow the owner's manual for replacement, and you can refer to the following maintenance standards: platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Steps for replacing spark plugs: Open the hood, lift the engine's plastic cover, remove the high-voltage wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one, and check for any leaves, dust, or debris on the outside during removal, ensuring everything is cleaned thoroughly. 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 wires in the firing order and secure the cover. What happens if spark plugs fail: Damaged spark plugs 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, affecting the vehicle's normal operation. Severe spark plug erosion, such as pitting, damage, or melted electrodes, indicates that the spark plugs are ruined and should be replaced.
