- Inspect the spark plug for any signs of damage or wear. If necessary, replace it with a new one of the same size and type.
- Apply a small amount of anti-seize compound to the threads of the new spark plug to prevent it from seizing in the future.
- Insert the new spark plug into the socket and carefully thread it into the spark plug hole by hand. Make sure not to cross-thread it.
- Tighten the spark plug using the socket and ratchet, turning it clockwise until it is snug. Be careful not to overtighten.
- Reattach the spark plug wire to the spark plug by pushing it firmly onto the terminal.
- Repeat the above steps for each spark plug, one at a time.
