Okay I don't know much about my diesel (only had it 6 months, still reading and learning). I googled "pyrometer" and GMC. What comes up is for 2007 and older models. Mine's a 2018. Why is it I don't see a pyrometer for newer trucks? I've begun making sure I let it idle a while before shutting down, but I'd like to see a gage that said it is cool enough.
