Ford F150 - spark plugs

how to replace new spark plugs on a 2004 f 150 5.4 litre va 4 dr. any tricks

From everyone I know, they're nasty to work on. You might take it to the shop. I just had the plugs and wires on my 4.6 done, and it took the Ford mechanica a little over 3 hours in their garage. Ridiculous.

Lot of info on this site,

Soak with penitrating oil over night, warm the engine, Take your time, turn 1/4 back and forth, take your time, have lots of swivel and extension bars couple of short ones too. Take your time. I removed the PCM and brackets to get to the back one.

Expext a full day, 4 hours to 8 hours seems to be the average.

They sell a special tool if you break them off.

Check out this post, I think it has a lot of good pictures and good replies

And dont go bananas with penetrating oil, you will lock up your engine

mine cost 330.00 to do at the dealer on an 05 5.4 with one breaking off. seems like a good deal to avoid that nightmare.

I wouldnt warm the engine before i changed those plugs,thats a good way to strip them.Use the penetrating oil though.

I totally agree with all the above authors. Take your time. I think of myself as a decent do-it-yourself mechanic for fun, and it took me about four (4) hours total. It took me about an hour to take all the fuel rails, intake, and everything else off so that you can get to the plugs, then soaked them over night for about 12 hours in PB blaster and they all came out like a dream. The plug closest to the driver side and close to the firewall was a lot tighter because of the constant heat it takes. Take your time, I saved myself tons of money and did it in an afternoon, lube is the key though, next to taking your time. Good luck, research it on this site.

Kreston- unless you have a different truck than is showing in your profile, what you were working with is a whole different animal than the OP has. He is showing as having an '04 5.4 which would be a 3V. very much different than yours. Unless he is somewhat mechanically inclined and is pretty fearless, I would suggest taking it to a dealer that is used to doing them without breaking them. If he breaks a couple or three plugs, he'll probably be having it towed to the dealer anyway.

Bleamond- see my reply to Kreston.

i would suggest buying the lisle 65600 tool prior to changing plugs if you've never changed them before just in case very inexpensive and works great

i have changed plugs in my 05 5.4l in only took about 2-3 hours and i did not break any of them, i know im one of the lucky ones. I did what the tsb told me to. blow the top of the head off so nothing falls down the hole. then remove the cops from one side and turn them about 1/4 turn spray some carb cleaner down the holes and let sit for 20 min. know here is the real trick go really slow when taking them out. There is actually more room then u think. i have changed them in 97-03 and they have less room to work with. O and by the way use a 9/16 magnetic spark plug socket.
