After replacing spark plugs in a car, it is important to check the ignition coil wiring and perform a test start upon completion of installation. Spark plugs have a certain service life, and when reaching a certain mileage, issues may arise, necessitating timely replacement. Generally, the materials of original spark plugs vary, and they should be replaced every 30,000 to 60,000 kilometers. The following precautions should be taken when replacing spark plugs in a car: 1. Always purchase spark plugs that are the correct size for your vehicle model. 2. Before preparing for replacement, ensure the vehicle is turned off and cooled down for a certain period before starting the replacement. 3. Pay attention to cleanliness during the entire operation; make sure to wipe away dust and oil around the ignition coil. If contaminants enter the combustion chamber, it can cause serious adverse effects. It is advisable to wear gloves during the operation. 4. When tightening all screws, apply even force and move straight up and down to avoid cracking the threads.
