Basic Spark plug change on a 2004 Mach 1
Tools needed : 3/8 Ratchet , 5/8 Spark plug socket , 3/8 Extentions , 3/8 Torque Wrench , 10mm socket , 8mm Socket , Impact Gun , anti seize , spark plug gapper coin
I started on my passenger side first , and started by removing my intake tube from the throttle body. Using a 8mm socket
I simply just placed it out of the way
Now I removed the coil cover with a 10mm socket
Now the coil on plugs are exposed , you can simply unplug the pigtail connectors on top with your finger tips , and remove the coil on plug off from the spark plug.
With your 3/8 Ratchet / long extension / 5/8 spark plug Socket remove the spark plug from the cylinder head
With your new spark plug be sure to gap the plug to .054 , and apply a small amount of anti-seize to the threads
I installed my spark plugs by hand until snug, first , And then with the torque wrench installed each at 12lbs.
The same process is for all 4 , and when your finished just re-install the cover / intake
The driver side is more simple , all you have to do is remove the coil cover with the 10mm socket , and the same process.
Well that's all , hope this helped
