This factory service and repair manual for the 1998 Ford L8511 covers a medium-conventional straight truck in Base trim with two turbocharged inline-six diesels, the 8.3L (504 cu in) and the 7.2L (441 cu in). With one body style and one trim, the manual's procedures, specifications and torque values are organized around the two engines, keeping the 8.3L and 7.2L figures apart, while the wiring diagrams and diagnostics describe the single straight-truck chassis. It is a focused reference for a truck whose only real variable is which of the two sixes sits under the hood.
