Thanks, Trailer2. What's the tool the is used to drill out a broken glow plug? And what would the est. cost be if that had to be done at a shop? Hopefully, it doesn't come to that, but it's good to know just in case.
Also, do you know if I can simply replace the one bad glow plug or do I have to replace all the glow plugs at once. I've replaced spark plugs in gas engines and usually, it's recommended to do them all at once, since if one is out then the others are not usually far behind. Is that the case with diesel vehicles in your experience.
