Glow Plug Video and Pics

[harrys91rs]

I just replaced my glow plugs along with my injectors and decided to make a video and take some pics of an old plug in operation powered by a jump pack. I personally couldn't find anything on the glow plugs on the internet so here it is:
YouTube - 2000 F250 7.3 Powerstroke Glow Plug


Here's my favorite:





The glow plugs had about 130,000 miles on them and it was getting hard to start if I didn't plug in the truck below 30*, but it would start. You can definitely feel the heat coming off them with your hand! I think that particular plug read 0.5 ohms. Anyway, hope you like the pics and video.

Looks like you replaced some good GP's. There is a write up in the tech section that walks you through troubleshooting the GP system. But you are right that's what Glow plugs do, They Glow, lol!!!

Yea, I figured I had them all out for injectors, and had a couple bad ones. Might as well do all new and be done with it.

Im wondering how many bad ones I have. My truck wont start below about 50 degs. Unless its plugged up. Im thinking I need some ( or all ) new injectors.200K on the ol girl.

What makes you think injectors? Mine has 205k , and I am sure this is the first set of glow plugs through it. But no way am I changing Injectors.

No need to wonder, why not know for sure, could be simply a bad GPR?

I saw this thread a couple days ago but didn't have a chance to see the pic's or vid.

Do they normaly swell like that or is it just the cam, making it look like that? If not the cam now I know some of us have a hard time getting the old ones out.

A International Tech I know said they swell up from using ether. He said it will expand the plug to the point of not being able to remove them. You end up pulling the head , and cutting them off. Mine a few were tight but not impossible to remove.
