After spending big bucks at the dealership and other mechanical shops, I decided to try replacing this myself. I got a diagnosis from an engine scan at a local mechanic shop that told me which glow plug was bad. These plugs can be purchased in complete sets, but I chose to just replace just the bad one. Watch an online video or two if you've never done this before. It really is pretty simple.The most difficult part is removing the fender liner to access the glow plug. But even that is not difficult. You might as well order some new fender liner retainers while you're at it. Even though I was careful, I damaged a few retainers and a couple were missing anyway.Good luck.

Exact part for 2004 GMC Duramax with the LLY engine, correct packaging marking indicating manufacturing in Germany. Was more cost effective than dealer or Autoparts store, by fair amount. Those saving will pay for tools if you don't have them (a 1/4 Torque wrench, suggest manual vs electronic because the size of the manual can fit in but good luck with the electronic ones).Note: ACDelco 63G does not come with the nut for the wire (separate purchase here or the dealer) and you will want to replace them so pick some up ahead of time. The required nut is a M4; Thread Pitch: 0.7mm;These work https://www.amazon.ca/uxcell®-Serrated-Flange-Stainless-Steel/dp/B07JJFPK9YSpray with rust penetrant a couple times a couple days before, run engine for 5-10 minutes. Try easy to reach one first, take your time and not to hard if it isn't going leave it spray again move on to next. let it soak for while try again.
