2020 Chevrolet Spark Service and Repair Manual

This factory service and repair manual for the 2020 Chevrolet Spark describes a small four-door hatchback with one engine, the naturally aspirated 1.4L DOHC inline-four of 85 cubic inches, offered in ACTIV, LS, LT and Premier trim. A shop working on one of these spends most of its time in three places, engine management, the body electrical system and the chassis, and the manual treats each with its own procedures, specifications, torque values and diagnostic steps. Wiring diagrams cover the circuits that tie them together.

Known issues on the 2020 Spark. Owners have logged 19 complaints against this model year in the federal database, split evenly at the top: 6 on the electrical system, 6 on the air bags and 2 on the engine. Read as a service hint, that puts module and circuit diagnosis first, covering supply, ground and communication faults along with the restraint system's own self-test and stored codes, and it puts engine mechanical and management work behind them. Wiring diagrams and diagnostic routines for all three are part of this manual.
