This factory service and repair manual for the 2010 Chevrolet Optra covers a four-door sedan in Base trim with the 2.0L inline-four of 122 cubic inches, double overhead camshafts, naturally aspirated, on gasoline. What a manual for a one-engine, one-body car buys a technician is time: no checking a build record against several displacements before reading a clearance, no hunting for the right wiring diagram among competing body styles, and one set of specifications and torque values that applies to every car wearing this model year's badge.

Known issues on the 2010 Optra. This model year's federal record is empty, with no recalls and no owner complaints against it. The manual is written for the jobs themselves: engine mechanical work on the twin-cam four, fuel and ignition system specifications, cooling and lubrication service, transmission and driveline procedures, brake, steering and suspension work, torque values and clearances at each step, and the wiring diagrams and diagnostic charts that make an electrical fault traceable rather than a matter of swapping parts.
