1998 Ford LT9513 Service and Repair Manual
This factory service and repair manual for the 1998 Ford LT9513 trims the engine list to eight by dropping one of the two 10.3L listings, so the turbocharged 10.3L inline-six (629 cu in) stands alone at that displacement. It sits with the 10.5L six-cylinder (638 cu in), the turbocharged 12.0L six-cylinder (732 cu in), the turbocharged 14.0L, 14.6L and 10.8L inline-sixes (855, 893 and 661 cu in) and the turbocharged, aftercooled 11.1L (677 cu in) and 12.7L (774 cu in) inline-sixes. The medium-conventional tractor truck and straight truck in Base trim carry over, so the 1998 procedures, specifications, torque values, wiring diagrams and diagnostics are mostly about engines.
