2018 Chevrolet Bolt EV Service and Repair Manual

This factory service and repair manual for the 2018 Chevrolet Bolt EV takes a four-door hatchback with battery-electric drive through Base, LT and Premier specification. There is no engine section in the conventional sense; in its place sit the high-voltage battery, the drive unit and the charging and thermal systems, each with its own service sequence and safety prerequisites. Around them run the ordinary chapters — brakes, steering, suspension, restraints, body panels and glass — with the specifications and torque values that each job calls for.

Known issues on the 2018 Bolt EV. Owners have filed 73 complaints against this model year, and they cluster tightly: 24 on steering, 23 on the electrical system and 11 on the power train. That is a useful map for anyone opening this manual, because the three areas are covered in sequence — steering gear, column and assist diagnostics with their torque figures; power distribution, grounds, module communication and circuit diagrams; and the propulsion side, from battery and drive unit checks through to the fault codes that report them.
