How to Remove the Spark Plugs on a Vios?
2 Answers
Vios spark plug removal method is: 1. Clean the upper part of the engine, that is, the dust around the cylinder wires, to prevent dust from entering the engine when replacing the spark plugs; 2. Use a wrench to loosen the spark plugs in the engine. The spark plug is an important component of the gasoline engine ignition system, which can introduce high voltage electricity into the combustion chamber and make it jump across the electrode gap to generate sparks, thereby igniting the combustible mixture in the cylinder. The Vios is an entry-level family model under Toyota, with a length, width, and height of 4410mm, 1700mm, and 1490mm respectively, and a wheelbase of 2550mm. The car's digital instrument panel is covered with an optical lens, which can prevent the eyes from constantly moving back and forth between the road and the instrument panel, effectively reducing visual fatigue.
I've been driving a Vios for over ten years and have changed the spark plugs myself several times. Before disassembly, make sure the engine is completely cooled to avoid burning your hands. For tools, you'll need a 16mm spark plug wrench and an extension bar—some Vios models might require a ratchet wrench for assistance. Open the hood, and the spark plugs are located on top of the cylinder head, which is quite easy to find. First, disconnect the spark plug coil connector—be careful not to pull it too hard. Use the wrench to gently loosen the fixing screws or clips, then slowly remove the coil to expose the spark plug. Next, use the specialized wrench to turn the spark plug counterclockwise. The key is to turn it straight without tilting, as damaging the threads can be a real hassle. After removal, check the old spark plugs for carbon buildup or corrosion. Don’t buy tools that are too cheap, as a slipping wrench can be a headache. The whole process takes about 15 minutes, saving you hundreds of dollars from a shop visit. Handling it during regular maintenance can also make the car more fuel-efficient and durable.
