This factory service and repair manual for the 1991 Ford Topaz covers a single trim, the GS, offered as a two-door sedan and a four-door sedan and powered by the naturally aspirated 2.3L OHV inline-four on gasoline. One engine and one trim make for a compact manual: the procedures, specifications, torque values, wiring diagrams and diagnostics are written for the 2.3L without variants, and the only branching the reader encounters is between the two-door and four-door bodies where their hardware is not the same.

Known issues on the 1991 Topaz. No recalls and no owner complaints are on federal record for the 1991 Topaz, so NHTSA holds nothing against this model year. That leaves the manual's coverage as the practical reference: procedures, specifications, torque values, wiring diagrams and diagnostics for the naturally aspirated 2.3L overhead-valve inline-four and for the GS in its two-door and four-door sedan forms, from engine work through the electrical system, with the same material serving both bodies except where they differ.
