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.
