This factory service and repair manual for the 2008 Chevrolet Optra applies to one specification and no other: a four-door sedan in Base trim, powered by the naturally aspirated 2.0L inline-four of 122 cubic inches with double overhead camshafts, running on gasoline. One engine, one body and one trim make the book unusually direct to use, because there is no branch to choose before a torque value, a clearance or a wiring diagram applies, and every procedure in it was written for the car standing in front of you.
Engines covered

Known issues on the 2008 Optra. The recall column and the complaint column are both empty for this model year at NHTSA. The manual's value here is preventive rather than corrective. It gives engine mechanical procedures and specifications for the twin-cam four, fuel and ignition system service, cooling system work, transmission and driveline overhaul, brake, steering and suspension adjustment with the torque values each step requires, and wiring diagrams with diagnostic charts for the sedan's electrical circuits.
