This factory service and repair manual for the 1991 GMC Tracker is written for the two-door sport utility in Base trim with the 1.6L SOHC inline-four, 98 cubic inches, naturally aspirated. Small four-wheel-drive vehicles of this era tend to outlive their parts catalogs, and a factory book becomes the reference of record: what the specification actually was, what a fastener torques to, and how a circuit is meant to be wired. All of that is here, arranged by system alongside the diagnostic procedures.

Known issues on the 1991 Tracker. The federal record is clean for this model year — no recalls, and no owner complaints logged with NHTSA. On a vehicle this old, the real issues are the accumulated ones, and the manual meets those on their own terms: engine mechanical and fuel system procedures for the 1.6L four, transfer case and axle service, brake and steering work, published specifications and torque values, and wiring diagrams tied to the diagnostic steps that use them.
