How to Replace the Spark Plugs on a Baojun 510?
2 Answers
Baojun 510 spark plug replacement steps: Open the hood, lift the engine's plastic cover, 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 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 removed high-voltage distributor wires according to the firing order, then secure the cover. Spark plug replacement interval: Under normal maintenance conditions, replace them 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 owner's manual. Refer to the following standards for maintenance replacement: Platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers.
I've changed the spark plugs at home many times, and it's quite simple for the Baojun 510. Prepare the tools: a 16mm spark plug wrench, new spark plugs matching the original model (don’t buy the wrong ones), and gloves to protect your hands. Step one: Open the engine hood and disconnect the negative battery cable to prevent short circuits. Step two: Remove the ignition coil connector—pull it out gently without damaging the wires. Step three: Use the wrench to unscrew the old spark plug counterclockwise, noting how the old one was installed. There might be carbon buildup, so clean the surrounding area if needed. Step four: Apply some insulating grease to the new spark plug, carefully place it back into the hole, and tighten it clockwise. The torque shouldn’t exceed 20 Nm—hand tight is enough, don’t overdo it. Finally, reinstall the ignition coil and reconnect the battery. After the replacement, start the engine to test it. If it runs smoothly, you’re done. Normally, you should change them every 30,000 km—it saves money, keeps things hassle-free, and improves throttle response.
