can you change the spark plugs on 2003 expedition like any other plugs finding them was hard but changing them how?
I found the spark plugs on my expedition now how do you change them I have never seen plugs with a wire connected to them can I just unplug the clip and change it?
Hi 25mal, The spark plugs are located below the coil in a hollow tube in the head. You must remove the spark coil retaining screw to access the removal of the spark coil. This will expose the spark plug at the bottom of the hollow tube in the head. The spark coil is about 6-7 inches long. Once removed you will see the spark plug at the bottom of that tube. There is no typical spark plug wire attached to the coil. Find the top of the spark coil (about 1-3/4-2" in diameter). There's a single small metric bolt holding the spark coil in place. It will not come out until that screw is removed. Good luck!
