Information...
"Information"... can sometimes be the hardest "thing" to acquire for any type of service project. It's hard because the best information can only come through personal first-hand and long-term experience. When I first discovered that my trucks needed new head gaskets I began the process of collecting the tools I needed to do the job. I already had a full set of GM service manuals, but as good as they are, they were written by tech writers who likely had never turned any wrenches on these engines, did not own one of these trucks and had probably never even driven one. Their knowledge was useful and important, but it was all theoretical.
In the beginning, I searched the internet for information, to help gain a better understanding of what was involved in a Duramax head gasket and injector replacement. What I found was a little disappointing. None showed you how to actually do the hard parts nor did they explain why certain processes had to be performed. No one explained how the special tools were to be used or answered the question of why these parts failed in the first place. Not having the necessary information in a video or written description is one thing, but I also found videos and forum posts that could actually be harmful to your Duramax. The most-watched 1-hour video on Youtube, about changing Duramax head gaskets, would almost certainly result in damaging your engine - if you followed their recommendations. The irony here is that this was a 1-hour video of a procedure that requires a minimum of 40 hours to complete. All of the hard parts of the project were left out, and instructions for using the special tools were left out. Head/block deck prep shown in that video would almost certainly result in damaging your engine. And, there was no long-term followup to show whether the repair was successful.
The Duramax head gasket replacement and injector replacement are both complex procedures that require excellence. Failure not only wastes tens of hours of your time, but it could also cost you thousands of dollars in replacement parts. Everything has to be done correctly. No one wants a do-over... It's just far too costly.
This new Service Guide answers every question I had about how to do the best job possible - every step in the process is explained in ways that complies with GM's service recommendations and standards and practices, even though a series of brand new and innovative ways of performing some of the procedures were introduced. This new Service Guide explains how to produce the best result without spending more than you need to. This new Service Guide explains how to perform this work in your home garage without a vehicle lift, and without pulling the engine or lifting the cab. You can also be assured that the two Duramax 6600 engines used to produce this Service Guide continue to provide routine service after more than a year and many thousands of miles later - without a single problem.
The large clear photos and written instructions both show and explain the details that no one else does. In May of 2021 my local GM dealership quoted me $7300.00 for just replacing the head gaskets in my 2001 GMC Duramax 6600. That quote only included new gaskets, new factory head bolts and decking the aluminum cylinder heads - and nothing else. With this Service Guide, you could complete the project for just a few hundred dollars... and this includes buying the few special tools shown in this Guide. Even if you hire someone else to do the work for you, this Service Guide can be used by them to do the best job possible or be used by you to verify their work.
