Glow plug removal / installation

Ok so I've been doing a lot of reading and I can't find a concise answer to the proper way to remove the glow plug rail and glow plugs.

I've been getting a P0674 code (I think that's right, doing it from memory) for the #4 glow plug and I bought a new one just in case. Going to pull the #4 plug and test the resistance.

I read up on the glow plug thread in the tech files but that just talks about how to test your glow plug resistance not the actual steps required.

Regarding the steps required I've read numerous ways and numerous ways that contradict each other.

Use the ford tool
Just pull it off
Don't pull it off
Use a coat hangar
Use a piece of wire
etc
etc

So... For you weekend driveway wrench monkeys, what's the best way to change out the glow plugs?

Yeah from what I've read the driver's side is easy to swap out. Just pull the aircleaner assembly out and you're there. It's just getting that rail / harness off that I've found all the contradictory information on.

i did mine w/ the head off. But i found that if you put a little wd-40 or equivalent on the plug end then use the tool or a homemade one to wriggle it gently back and forth it will pop out eventually. I found the key to not breaking them was to be as gentle as possible and just work it back and forth. Now with that being said one side came off flawless, the other i broke two plugs on the harness. Then i just yanked them out by the wires after they were already broken. After you have the harness off the glow plugs are just underneath. A 10mm deep well socket and a magnet will take them out.
Good Luck,

Thanks Triton, where'd you get your new harness from? Did it come with the complete rail for all 4 on that side of the motor? I'm just trying my hardest to not break them since the stealership wants $376 for the new glowplug rail should I break any and I haven't been able to find anywhere online that sells it.

I just called the dealer they said they are about 65 bucks retail each side. I think they quoted you a price for a injector harness

yeah from what i recall the part number is:

Glow Plug Harness -
Ford P/N - 4C2Z-12A690-AB for the passenger side

-5C3Z-12A690-A for the driver side

i looked the p/n up back when i did the job because i had a broken one. When i pulled the broken ones out by the wire with the pliers, it just scratched the jacket on the wires, so i just put electrical tape over the bare part and put the broke one back in.. No codes yet, we'll see come winter.
