Spark Plug Change 2005 F150 5.4 Triton
Changing the spark plugs on a 04-late 07 Ford Triton engine can be a scary task. Especially for someone like me who isn't a mechanic. Just do a quick search and you will find forum after forum talking about spark plugs that have broke off while trying to remove them. Ford decided to use a two piece spark plug for some reason. Even with all the warnings I still decided to go about the change myself. Here was my process with only one broke plug.
First I made sure I had all the necessary tools to get the job done correctly. I ordered Kroil which is a phenomenal penetrating oil (first time using it). I also bought the Lisle broken spark plug remover tool which is specifically designed for these plugs. Of course I had the new spark plugs on hand and a spark plug socket.
The night before I went to perform the change of plugs I removed the coil packs and sprayed the Kroil into the spark plug well to let it soak over night. To say I was very skeptical about it helping at all would be an understatement.
So the next morning I decided to start on this endeavor. The first five spark plugs came out with little to no problems. I could tell right away that the Kroil had managed to soak its way into the threads to help remove the plugs. Right then I knew it had helped.
The sixth spark plug though was a different story. This was probably due to user error as I might have tried to remove it at a weird angle thus breaking the porcelain and leaving the other half of the spark plug in the head. This is where the Lisle spark plug remover tool was worth the money.
The Lisle tool is very easy and fairly quick to use. One part pushes the broken porcelain into the remaining metal end that is in the head. The other then threads into the metal and pulls it all out of the head. After that it was smooth sailing.
With all the plugs out and things cleaned up as best a possible it is just a matter of backtracking and putting in the new plugs and putting back on the coil packs. I won't say that it is a quick task but if you are willing to give it a try it can save you hundreds of dollars to do the spark plug change yourself!
