What size is the Vios spark plug wrench?
2 Answers
Vios spark plug wrench is a 16 spark plug socket. The spark plug, commonly known as the sparking plug, functions to discharge the pulsed high voltage sent by the high-tension wire, breaking down the air between the two electrodes of the spark plug to generate an electric spark, thereby igniting the air-fuel mixture in the cylinder. The main types of spark plugs include: standard spark plugs, projected insulator spark plugs, electrode spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs, among others. The Vios is a family-oriented entry-level model specifically designed and developed by Toyota for the Asian market. With an extended wheelbase, the Vios offers more ample interior space, and the rear legroom is satisfactory. The overall interior has a technological feel.
I've been driving my Vios for several years and have changed the spark plugs multiple times myself. The spark plug wrench size is usually a 14mm deep socket wrench because the Vios engine design is deep, and tools that are too shallow won't reach the position. Mine is a 2018 model, and the manual clearly states 14mm, but I recommend checking your specific year and model, as earlier models might be the same. When spark plugs age, starting the car becomes difficult, and fuel consumption increases, so I check and replace them every 30,000 kilometers. The tools aren't expensive; you can get a set online for just over ten bucks. Make sure to choose one with a rubber head to protect the electrodes, and don't buy cheap ones that are prone to stripping. It's best to work on a cold engine to avoid burning your hands, and be gentle when removing the spark plug wires to avoid breaking them. After replacing them, the engine runs smoother immediately, and acceleration feels more responsive.
