This factory service and repair manual for the 1990 GMC Tracker documents an unchanged formula in its second year: one Base trim, one body — the two-door sport utility — and one engine, the naturally aspirated 1.6L SOHC inline-four of 98 cubic inches. Because so little varies, the manual can go straight to procedure. Each system, from engine mechanical through the drivetrain, brakes, steering, suspension and body, is set out with its own service steps, published specifications, torque values, wiring diagrams and diagnostic checks.

Known issues on the 1990 Tracker. No recalls sit on the federal record for the 1990 Tracker and no owner complaints are logged with NHTSA. Nothing therefore points a technician at a particular weak spot, which puts the emphasis back on method: correct clearances on the 1.6L four, correct torque on the fasteners a job disturbs, and a wiring diagram in hand before a circuit is probed. The manual supplies all three, along with the diagnostic sequences that accompany them.
