Steps to Replace Spark Plugs
If you’re planning to replace the spark plugs in your 2006 Expedition, here are the general steps to follow:
- Ensure the engine is cool before starting any work.
- Locate the spark plugs. They are typically found on the top of the engine, connected to the ignition coils.
- Remove the spark plug wire or ignition coil from the spark plug by gently pulling it straight out.
- Using the appropriate spark plug socket and a ratchet or extension, loosen and remove the old spark plug by turning it counterclockwise.
- Inspect the spark plug for any signs of damage or wear. If necessary, replace it with a new one of the same size and heat range.
- 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, ensuring it is properly aligned.
- Tighten the spark plug using the socket and ratchet, turning it clockwise until it is snug. Be careful not to overtighten.
- If you removed an ignition coil, reattach it to the spark plug. If you removed a spark plug wire, push it back onto the spark plug until it clicks into place.
- Repeat the above steps for each spark plug, one at a time, until all have been replaced.
