The information contained in this Guide is 100% original to The Diesel Page. Throughout the years, we've spent considerable time in an engine rebuilding facility, toured the AM General/GEP 6.5L diesel engine plant, answered tens of thousands of technical and troubleshooting questions from as many 6.2/6.5 diesel owners, and have developed dozens of brand-new and original solutions to 6.2/6.5 diesel problems. But perhaps most important is our nearly 24 years of first-hand ownership experience with the GM 6.2L, 6.5L and Duramax diesel engines. All of this information was compiled into a 98 page (8-1/2 x 11) Guide that is both easy to read and understand. In most cases, individual aspects of engine problem diagnosis include theory of operation, which will help you understand why things work the way they do. Knowing the "how and why" of system operation will help a diesel owner analyze individual problems and help provide a long-term solution.

We've performed nearly every conceivable maintenance operation possible with these engines and have learned what it takes to get the most out of them. This Guide will show you parts of your engine you've probably never seen, and will explain many innovative and money saving maintenance procedures not discussed in any other manual of this kind. This Guide is a "must have" for any 6.2L/6.5L owner.
