2007 Chevrolet Cobalt Service and Repair Manual

This factory service and repair manual for the 2007 Chevrolet Cobalt documents three four-cylinder engines, two of them naturally aspirated, the 2.2L DOHC of 134 cubic inches and the 2.4L DOHC of 145, and one supercharged, the 2.0L DOHC of 122. All three were fitted to the same pair of bodies, a four-door sedan and a two-door coupe, in LS, LT, LTZ and SS trim. Engine-specific data is what a technician looks up first here; the chassis and body sections then apply across the range.

Known issues on the 2007 Cobalt. Six recalls are recorded for this year. Two of them describe fuel pump assemblies that can leak, with fire possible if the leak finds an ignition source. Another two concern the ignition: the key can be removed while the switch is not in the off position, allowing a rollaway, and a switch that slips out of run stalls the engine and leaves the air bags unable to fire. Sudden loss of electric power steering assist accounts for another. Of 1,564 complaints, 688 are on steering, 260 on fuel and propulsion and 185 on the electrical system.
