This factory service and repair manual for the 2023 Chevrolet Aveo documents the sedan in LS and LT form with the 1.5L inline-four of 91 cubic inches, naturally aspirated and gasoline-fueled, under double overhead camshafts. Its organization follows the vehicle rather than the sales brochure: the engine and its management systems first, then the transaxle and driveline, then the brakes, steering and suspension, then climate control, body, trim and the electrical circuits, each with the procedures and figures the work requires.

Known issues on the 2023 Aveo. This year has drawn neither a recall nor a single owner complaint. The manual is accordingly a reference for maintenance and repair, and it is written to be used at the car. Procedures give the order of operations and the torque values; specifications cover clearances, pressures and electrical values; wiring diagrams show connectors and grounds as installed; and diagnostic charts turn a symptom into a test sequence instead of a list of parts to try.
