1988 Ford LTS8000 Service and Repair Manual
This factory service and repair manual for the 1988 Ford LTS8000 splits its attention between two medium conventional bodies, a tractor and a straight truck, while the engine list holds steady at one, the 10.4L V8 diesel of 636 cubic inches. Base trim covers both. Whether the truck is pulling a trailer or carrying a body on its own frame, the engine procedures, specifications and torque values are identical, and the wiring diagrams and diagnostics are organized so that the shared content stays shared.
