This factory service and repair manual for the 1988 Ford L8000 covers the medium-conventional straight truck in Base trim with its 10.4L V8 diesel (636 cu in). That is the whole lineup for the year, one engine, one body style and one trim, so the manual's procedures, specifications and torque values describe a single truck and its wiring diagrams and diagnostics chart a single chassis. For a shop, that means the diesel V8 figures and the straight-truck chassis references can be applied directly, with nothing to cross-check against a second engine or chassis.
