1991 Geo Storm Service and Repair Manual

A second body joined the Storm for 1991: a hatchback whose squared-off roof gave rear passengers far more headroom than the 2+2 fastback coupe. The hatchback and the 2+2 used the 1.6L SOHC four-cylinder, and the GSi coupe kept its 130-hp 1.6L DOHC engine. This service and repair manual is matched to the 1991 Geo Storm lineup, with procedures, specifications, torque values, wiring diagrams, diagnostics and maintenance schedules for both engines and both body shells, including the hatchback's own rear body details.
