Glow Plug Removal

[theoldpoop]

Does someone know what size socket I need to remove the glow plugs?? Are there any tricks to successful removal and re-install. Thanks for the help, POOP.

The socket size needed is a 10mm deep. I also suggest having new glow plug harnesses in your hands as well as the glow plugs themselves before you get your hands dirty with this job. Even with the proper Ford/Rotunda tool, they tend to break when you attempt to remove them. Cylinders #5 and #7 will be a lot of fun to access with the evaporator housing in the way.

oh my, those glow plug harnesses are a pain in the ***. I wish I could offer some tips or insight but I haven't figured this out 100% for myself

Try soaking each connector with LIBERAL amounts of PB Blaster or penetrating fluid and wiggling it about before you attempt to disconnect it.

Okay, I got my 10mm deep and was working om the driver side glow plugs. When I try to remove the harness cap, it comes out about an inch exposing a plastic strip or something??? What is going on here??? Your thoughts PLEASE??

10mm deep socket, short extension. Removing the inner fenders helps tremendously. To get them out, I use a small piece of vacumn hose to slip over the tip. I'd recommend ordering new harnesses now, as they are very likely going to break.

But what is this filamentstrip I see whenn I pull the cap off. I don,t want to cut. I am LOST HERE HELP

I've had some luck with a heat gun on the harnesses-seems to heat up the o-rings so they slide out easier.

Filament strip? Pull the cap off? The glow plugs are accessible without removing the valvecovers.

Okay, From the top, My 05 stock 6.0 is hydro locked and I am in the process of newbie tear down. Everybody has been more than helpful with step by step PDF's and advice. Thank GOD. I have wrenched on tractors and misc. but never anything this packed together. I have been dis-mantling by the book and am at the point I can see what I think are the glow plugs. Members have told me that since I am hydro locked that if I remove the glow plugs and crank by hand the dead engine I will relieve the cylinder lock. That is where I am at this point of dis- assembly. If I am actually at the glow plug, it has a snug wiring harness running along the lower portion of the valve cover. IF,I try to pull the lead off the four plugs on the drivers side ,,, it moves out about an inch exposing a yellow or red (looks to be plastic) filament running down the center of the g plug. What NOW. Don't want to rip and tear. Want to proceed with expert advise. Thanks POOP

And this would be where the glow plug harness has already come apart. You will now need to replace the harness with a new one or you will have oil leaks, if you even think about re-using it. I stated it once, and I state it again. Soak the bores where the each of the four connectors plug into the glow plugs themselves through the rocker arm carriers with LIBERAL amounts of PB Blaster or WD-40 and wiggle them about. Give each connector a light tug and they should come out. Finesse will be your best friend here.
