Does Changing Spark Plugs Outside the 4S Store Affect Warranty?
1 Answers
Changing spark plugs outside the 4S store does not affect the warranty. If the spark plugs are within the warranty period, you can replace them at the 4S store or do it yourself. The specific replacement steps are as follows: Open the engine hood, lift the plastic cover of the engine, remove the high-voltage distributor 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 leaves, dust, or debris on the outside and ensure they are cleaned thoroughly. 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 high-voltage distributor wires according to the firing order and secure the cover. Spark Plug Replacement Interval: Under normal maintenance conditions, spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's recommended to follow the user manual. You can refer to the following standards for maintenance replacement: Platinum spark plugs should be replaced every 40,000 kilometers, standard nickel alloy spark plugs every 20,000 kilometers, and iridium spark plugs every 60,000 to 80,000 kilometers.
