2010 Chevrolet Cobalt Service and Repair Manual

This factory service and repair manual for the 2010 Chevrolet Cobalt lists five trims, Base, LS, LT, LT Team Canada and SS, against two bodies and two engines. The engines are the naturally aspirated 2.2L DOHC inline-four of 134 cubic inches and the turbocharged 2.0L DOHC four of 122; the bodies are a four-door sedan and a two-door coupe. Trim level mostly changes equipment rather than mechanicals, so the branching a technician meets in the book is between the two engines and the systems that support them.

Known issues on the 2010 Cobalt. Six recalls are recorded here. Two describe electric power steering assist that can be lost suddenly, leaving heavier steering effort at low speed. One describes a side-impact sensor harness misrouted in the driver's door, which can disable the driver's roof-rail air bag so it cannot deploy. Others cover the ignition switch, both a key that can be removed with the switch out of off and a switch that leaves the run position and disables the restraints. Of 583 complaints, 241 concern steering, 88 fuel and propulsion and 82 the electrical system.
