Ford Triton Spark Plug Removal
I am going to attempt to replace the plugs on my 2005 4.6L Triton next week. Anybody have any useful tips?
I have been running 93 octane and just ran a bottle of Marvel Mystery oil then injector cleaner. I really dont want to break a plug. Any tips would be greatly appreciated. |
Yes!
Im a gm dealer Had one of my guy change those on a trade we got Long story short it costed me a complete engine! Spark plug broke like it usually does. If you dont have the vacuum and special tools to do it, dont do it! If you do it, it might take you like 5 or 6 hours Make sure you bring each cylinder you are taking the plug off in its upper position, so if you have broken pieces of spark plug in the cylinder, you might be able to take them out with a shop vac or something like that. If piston is down, you are dead!!! |
The best luck I have had is get engine hot then pull 2 coils and use a 3/8 air impact on the socket. I do 2 at a time getting engine hot between attempts for them not breaking. They are 9/16" socket on the plug if you were not aware. I have tried many methods and everybody has always said you never want to remove plugs on a aluminum head engine when they are hot but have never damaged threads on them. The sudden jolt of the impact is what breaks the carbon loose. If they do break Lisle makes a tool to remove them that works well for around 70 bucks .Good Luck!

I suggest taking it to a professional that works on these engines regularly. I've never done it, BUT there is a special tool that a couple of the tool wagons sell for this job, including getting out broken plugs. IMHO, it's not worth the risk.

Plug change at 60k? That seems early considering how many 100k plugs are out there these days........
Probably should change them in my wifes tahoe - 130k on the originals..... |

For those that don't know the Ford 5.4L in one if it's iterations has a REALLY bad spark plug design. Take a look here:
[ATTACH=CONFIG]540542[/ATTACH] They have a TERRIBLE habit of breaking off below the threads. I fully support the replacement of them while under warranty as JS indicates his direction above. I'd do the exact same. |

There are some that use a 3/8 cordless impact to remove the spark plugs with success. There is a TSB on how to do it from Ford. Knock on wood when I did mine they came out with little carbon build up as I only use quality super unleaded fuel. Carbon build up is the key issue. On customers vehicles I run a whole can of "Seafoam" thought the intake first. This helps also to soften the carbon build up. I have the removal tool and have yet to use it.
