1988 Ford LTS9000 Service and Repair Manual
This factory service and repair manual for the 1988 Ford LTS9000 pairs three turbocharged inline-six diesels, the 10.0L, 14.0L and 14.6L, with the medium conventional tractor and straight truck, both in Base trim. The engines share a layout and a method of aspiration but not their internal dimensions, so the manual keeps clearances, torque values and rebuild specifications distinct for each. Wiring diagrams and diagnostic procedures are organized by system and apply across both bodies.
