The method for replacing spark plugs in a Sail is: 1. Remove the engine cover; 2. Clean the dust and oil around the high-voltage wire terminals, then unscrew the fixing screws; 3. Remove the high-voltage wire terminals and loosen the spark plugs; 4. Insert the hose from the high-voltage wire terminal into the combustion chamber and pull out the spark plug; 5. Tighten the new spark plug into the high-voltage wire terminal and secure it with the clip. Precautions for replacing spark plugs in a Sail are: 1. Do not use excessive force or shake the spark plug insulator when removing the high-voltage wire terminals; 2. Wait for the engine to cool down before opening the engine guard plate; 3. Keep the spark plug electrodes and sealing washers clean.
Last time I replaced the spark plugs on my Sail by myself, and it went pretty smoothly. The key was preparing the tools and being careful during the operation. First, I bought new spark plugs, making sure the model matched the OEM specifications for the Sail. I gathered a wrench, spark plug socket, and gloves—safety first—then disconnected the negative battery terminal. I popped the hood and located the spark plugs, which were on the engine cylinder head. Using the wrench, I removed the wiring from the old spark plugs and then slowly unscrewed them. It’s important not to use too much force, as they can break inside. When installing the new spark plugs, I screwed them back in gently, ensuring they were properly seated but not overtightened. Finally, I reconnected the wiring, reattached the battery, and started the engine to check if it ran smoothly. The whole process took about an hour. If the spark plugs are severely worn, they can affect fuel efficiency and power, so it’s important to replace them regularly—check them every 30,000 kilometers.
