Cummins Diesel Engine Performance Haynes Techbook Paperback – February 25, 2020

I bought a new copy of the book of which arrived undamaged and clean. The book contains a lot information on the Cummins engine how to repair specific things along with tips on maintenance and what to look for with plenty of pictures to complement it. I am using the book to help create an upgrade plan for my truck on what modifications to get and install in what order since it is based what your end goal is since my own is towing a recreational vehicle first with performance second.

This is a must have with a 5.912 valve

Husband has both a Ford and now a Chevrolet 3500 diesel so he can repair and maintain the vehicle

Book has all the torque specs I needed and very detailed.

It is an OK manual for the Cummins diesel line.

excellent book

Super price.

I find the book to be filled with a lot of unnecessary info for someone that's looking for a repair manual.
