How to Remove the Spark Plugs on a Toyota Vios?
2 Answers
Toyota Vios spark plug removal steps: 1. Perform the operation when the engine is cool, and prepare the necessary tools including a wrench, socket, and adapter; 2. Disconnect the electrical connector and remove the ignition coil. In all gasoline-powered vehicles, the spark plugs are located beneath the ignition coils, with an accompanying power supply plug nearby; 3. Unscrew the spark plugs. Next, use an appropriate socket to loosen the spark plugs, ensuring gentle movements to prevent dust from entering the combustion chamber. The Toyota Vios is a compact car with a 4-door, 5-seat sedan body structure. Its dimensions are 4435mm in length, 1700mm in width, and 1490mm in height, with a wheelbase of 2550mm. The suspension system features MacPherson strut independent suspension at the front and a torsion beam non-independent suspension at the rear.
As a seasoned driver of a Vios, I often change the spark plugs myself. First, ensure the engine is cool and turn off the ignition for safety. Gather the necessary tools: a spark plug socket, wrench, and new spark plugs, plus cleaning supplies. Before removal, disconnect the ignition coil cables and gently wiggle them to avoid damage. Use the socket to loosen the old spark plugs clockwise, then carefully pull them out to prevent dust from falling into the cylinder. Clean the threads in the hole, apply anti-seize compound, and install the new spark plugs. Tighten them with moderate force—neither too tight nor too loose—I usually aim for 15-20 Nm to avoid leaks or broken threads. Finally, reconnect the cables and start the engine for a test drive. Remember to replace them every 40,000 km to keep the engine running smoothly. DIY saves time and money, and regular checks can extend your car's lifespan!
