1 Answers
Volkswagen Tiguan spark plug replacement steps are as follows: 1. Unplug the ignition coil wiring harness connector and remove the ignition coil fixing bolts; inspect the spark plugs (check if the terminal is damaged, if the insulator is punctured, if the electrodes are worn, etc.). 2. Select the appropriate tool to remove the spark plugs and take them out; cover the spark plug holes on the cylinder with a clean cloth to prevent objects from entering the cylinder interior. 3. Align the ignition coil with the spark plug, install it in place, use a tool to screw in the bolts, clean the measuring tool, measure the spark plug gap, and evaluate the spark plugs. 4. Check the new spark plugs for any appearance issues, place the spark plug into a dedicated socket, screw it into the spark plug hole using a digital torque wrench, tighten the spark plug, turn off the ignition switch, open the hood, and install the three-piece set. 5. Use a digital torque wrench to tighten. Start the vehicle, clear any faults, and tidy up the work area.
