Glow Plug Replacement
I have to replace the #6 glow plug. I confirmed it is bad and the harnes broke when trying to reove it with the proper tool. I ordered a new glow plug, ZD13, and a new drivers side harness.
I have never replaced a glow plug before but it seems pretty straight forward. I watched some youtube videos and did some reading.
I have read some state that you have to loosen the glow plug with a 10mm socket and then take some tubing and push it onto the glow plug to finish loosening it and prevent it from falling into the cylinder. I have read people saying it took them hours with a magnet to get the plug out of the cylinder.
If the plug is threaded and is removed from the threads how is it possible for it to fall past the threads into the cylinder?
Anything special I need to know? Anti-seize on the threads and dielectric grease on the connection? Any idea what the torque spec is?

I replaced the driver side GPs but did not do the passenger side due to time required. PITA but doable. There is a YouTube video for changing the passenger side. I think this is what I did. Been a while. Removed power strip. Got a 10mm deep socket and gorilla taped it to the extension. Loosened the GP then took a good strong magnet and pulled the GP out slowly until I got my finger on it. The GP was still in the hole when I grabbed it just in case I dropped it I would not have to remove the valve cover to get it. When installing be sure it is in the hole before you let go of it. Recommend you put some dielectric grease on the new power strip connectors.

I just did all of mine
I was able to turn the glow plug until I could feel the threads no longer engaging and then put a little downward tension on the extension and pulled it and the socket back. The glow plugs came right out. I also put the new ones in by hand and had no issues finding the holes and not being able to handle the glow plugs.
