This factory service and repair manual for the 2009 Chevrolet Optra narrows to a single car: the four-door sedan in Base trim with a 2.0L inline-four of 122 cubic inches, naturally aspirated, twin-cam and gasoline fueled. Nothing in the specifications depends on which engine or which body the original buyer chose, because there was one of each. That makes this a straight reference, where the procedure for a job is the procedure, and the torque values and clearances printed beside it apply without qualification.

Known issues on the 2009 Optra. This car comes through the federal record without a mark on it, no recall and not one owner complaint at NHTSA. The manual covers the work regardless: mechanical procedures for the inline-four, fuel, ignition and emissions specifications, cooling system service, transmission and driveline procedures, brake and suspension work, steering service, torque values throughout, and the wiring diagrams and diagnostic charts needed to trace a fault in the sedan's electrical systems.
