International/Navistar Inline 6 Service Manuals
International (Navistar) factory service manuals are an excellent way to reduce diagnostic & repair time. Why use an aftermarket manual that may not have all the information needed to do the job properly? Why not pay a bit more and use the same service manuals used by the Navistar dealers? Whether you are working on the mechanical aspects of the engine or are involved in diagnosing electronic engine control problems, we have you covered.
