This factory service and repair manual for the 1985 Ford LTS8000 addresses one truck and one engine: the medium conventional straight truck in Base trim, powered by the 636 cubic inch, 10.4L V8 diesel. The simplicity is useful in a shop, because every torque value, clearance and diagnostic step in the book belongs to that combination and no other. The engine, fuel, cooling and electrical sections are set out by system, with the wiring diagrams placed where the diagnostics call for them.
