use a screw to remove glow plug harnesses

[04cr450]

this is the best method to removing stubborn harnesses.. Mine were a pain, i broke every last bit of the glow plug harnesses in trying to get them out.. I used a 2 inch drywall screw and drilled in the center of plug(theres plenty of romm below plug so u wont hit the valve springs etc)... Used a pair of pliers and wiggled rough.. Plugs came out.. sheeeeww what a freaking job, way to go ford on your messed up design...

Did you try to use the proper tool for pulling them?

A little PowderBlast, a little heat, and the wire trick is the best procedure to try IMO.

yup that isnt worth a dam... im still working on it though.. 2 of them are in there good and wont out. the wire and clip for tool broke so plug is flush with head... im so frustrated with this simple task... so basiclly im dead in the water as of now... any ideas on how to get these out now? thanks

Just took mine out last week to replace a glow plug. Took about 15 minutes from time I opened the good until I closed it. The engine was warm so that might have helped. Just pulled them and they all came right out without breaking. Had a new harness ready to go in anyway.

just got finished guys.. wow what a pain. I will do a full write up on it with pics... Mine were so bad to make the long story short, a couple of them i had to chisle them out literally... then made up a piece of hose on the end of the vaccum cleaner and stuck that down in the whole to get out any plastic pieces that may have fallin in there(none were found though) sooooo. removal all finished just waiting for my plugs to come in from tousley. u guys that have the write-ups on doing this job saying-"just pull them out"... HA! u got lucky my friends hahah:$

I've done quite a few sets and never had an issue. Now, 7.3's are a different story.

Im not sure why mine were so bad. They are the orginal ones(169,000 miles)... Also it was cold yesterday and truck sat for 8 days.. The plastic and rubber just fell apart when touching it.. Just bad luck with it.. Now i have all new ones so, neverseize on them and wont have this issue again. Pics later . thanks for the replys

Those harnesses are a pain, especially if you're in any of the corrosion states. It's mostly the oxidized aluminum from the rocker box that causes them to stick. that and the plastic gets brittle from years of engine heat.

The tool is nearly worthless. The best thing to do is to try and get them to rotate in the rocker box to free up the o-ring. They'll usually come right out after that. If you can't get the harness end to move in the hole be prepared to dig it out piece by piece

if for whatever reason you already have the valvecovers off just pop the harnesses out from the inside
