2021 Chevrolet Aveo Service and Repair Manual

This factory service and repair manual for the 2021 Chevrolet Aveo lists two trims rather than three, LS and LT, on the four-door sedan, with the naturally aspirated 1.5L DOHC inline-four of 91 cubic inches as the only engine. The trim reduction changes the equipment tables and some of the wiring, not the mechanical work, so the engine, transaxle, brake, steering and suspension sections apply to both cars, and the diagrams show which circuits belong to which level of equipment.

Engines covered

• 1.5L inline-four (91 cu in) — DOHC, naturally aspirated, gasoline

Known issues on the 2021 Aveo. The manual provides system-by-system documentation: engine mechanical and management for the 1.5L four, transaxle service, brake hydraulic and foundation work, steering and suspension procedures, climate control, and the body electrical circuits. Each comes with the specifications and torque values the job needs and, where a fault must be found first, a diagnostic routine to find it.
