How to Remove Glow Plugs

Model: (Various brands) Various
Part: Glow plugs

Video tutorial

In this video, you will see how to remove glow plugs. This work should be done with the engine warm, as there is a risk of breaking the glow plug inside (which can be quite troublesome).

It is not a difficult job, but it is delicate. As seen in the video, the position does not allow for a wide view, so you will need to work almost by feel.

When reinstalling, it is advisable to apply copper grease to the threads of the new glow plug. It is very important that the threads go in straight; if they are misaligned, they will need to be re-threaded.

It is always best to change them all at once, as shown by the YouTuber. After some trials, a start-up test is performed, and everything works perfectly.
