Explaination of three-character engine codes?
I suppose the "appropriate service information under General Information" is referring to the service manual, which I can order from, for example, Helm, Inc? Thanks for this information. Great to know!- MarkEHansen

Explaination of three-character engine codes?
I see references to three-character engine codes and have searched for an explanation, but can't find anything. Is there a sticky or some other reference where I can find these defined? Also, how to do I determine what I have? I just purchased a 2019 GMC 3500 Denali HD with the 6.6L Duramax...- MarkEHansen
