1991 Chevrolet Corsica Service and Repair Manual

This factory service and repair manual for the 1991 Chevrolet Corsica covers a single trim, LT, in two shapes — a four-door hatchback and a four-door sedan — with either the naturally aspirated 3.1L overhead-valve V6 of 189 cubic inches or the naturally aspirated 2.2L overhead-valve inline-four of 134 cubic inches, both on gasoline. One trim simplifies the equipment lists; two bodies and two engines keep the procedural sections precise, since torque values, wiring routes and panel operations are called out for the exact combination on the lift.

Known issues on the 1991 Corsica. One recall stands on the federal record, and it is a fastener problem with a severe end: the nut holding the steering wheel to the column may not have been tightened properly, and a loose one can let the wheel separate from the column while the car is being driven. Owner complaints are far more numerous at 133, concentrated in the electrical system with 28, exterior lighting with 27 and air bags with 20 — circuits, lamps and restraint diagnostics that this manual addresses with wiring diagrams, test procedures and specifications.
