2008 Chevrolet Astra Service and Repair Manual

This factory service and repair manual for the 2008 Chevrolet Astra takes in four gasoline four-cylinders — a naturally aspirated 2.0-liter of 122 cubic inches, two 1.8-liters of 110 cubic inches that differ in valve train, one with double overhead cams and one with a single camshaft, and a turbocharged 2.0-liter — across a four-door sedan and a four-door hatchback. Five trim designations appear for the year: Comfort, Confort, Elegance, Essentia and Sport. That spread shows up in the equipment-dependent wiring diagrams more than anywhere else in the book.

Known issues on the 2008 Astra. The book's value is in its procedures: separate mechanical specifications for the single- and double-overhead-cam 1.8-liter, boost and fuel control diagnostics for the turbocharged two-liter, transaxle and driveline service, suspension geometry and fastener torques, brake and hub work, air conditioning charge and diagnosis, and wiring diagrams keyed to the sedan and hatchback bodies.
