Steps to Replace Spark Plugs
If you’re unsure how to replace the spark plugs in your 2003 Ford Mustang, follow these steps:
- Make sure the engine is cool before starting.
- Locate the spark plug wires on the engine. They are usually connected to the top of the engine and run to each spark plug.

- Using the appropriate spark plug socket size from the chart above, attach it to a ratchet or extension.
- Place the socket over the spark plug and turn it counterclockwise to loosen and remove the spark plug.
- Inspect the old spark plug for any signs of damage or wear. If necessary, replace it with a new spark plug 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.
- Hand-tighten the new spark plug into the spark plug hole, and then use the spark plug socket and ratchet to tighten it further. Be careful not to overtighten.
- Repeat steps 3-8 for each spark plug, one at a time.
- Once all the spark plugs are replaced, reattach the spark plug wires by pushing them firmly onto the spark plugs.
