well i tested my glow plugs and 3 are showing dead. my glow light wont turn on, and the fuse is ok. so i wanted to remove the glowplugs but i cant. the threads are rusted and if i turn the wrench, then the nut/cable/threaded part all move but the main part of the glowplug stays in the engine.

if i try and turn the body of the glow plug, i can turn it in the direction to remove it, but then the wire starts moving and i am affraid of breaking that cable.

any suggestions?

You should have a small nut on the end of the plug that secures the wire. Remove the nut, carefully, and then remove the wire.

Then remove the glow plug.

the problem but of course you must remove the wires first... before removing the glow plug.

After removing the Glow Plug wires, then spray a good blast of PB Blaster
solvent around the threads of each GP. Wait for at least 15 minutes then try removing the GPs.

I'd recommend removing the IP lines too, my hands were too large to fit in there easily and ended up cutting myself up big time.

Make sure to have anti-seize on the threads too...

they pose a lot of resistance, spray the pb again and work them in and out each time coming a little more out. you dont want to break any off in the engine.

pardon my lack of knowledge, but what is pb? some form of anti-seize?

"pb" is "pb blaster" kinda like liquid wrench but much better. you can buy it just about anywhere(walmart,autozone,ect) also sears has a cheap ratcheting wrench that doesnt have any angle to it. works really well for removing them.

Hey everyone, let's suppose these things won't budge and the core of the
glowplug is turning and the small wire retaining nut is really, really frozen.

How about busting the end off, maybe with a chisel - gently..
Let the frozen nut and threads fall, saving the wire.

Remove the old glowplug body (I prefer WD-40 to loosen threads).
When all GP are free, remove the harness if needed and clean it up.

Get some new nuts for the glowplugs and reinstall, and promise to yourself
to never wait that long again to cycle these things out.

Just my thoughts..... I might be wrong.
