2009 Chevrolet Avalanche Service and Repair Manual

This factory service and repair manual for the 2009 Chevrolet Avalanche is written for a four-door crew cab pickup in Base, LS, LT and LTZ trim, powered by one of two naturally aspirated overhead-valve V8s — the 5.3-liter of 325 cubic inches, flex-fuel or gasoline, and the 6.0-liter of 364 cubic inches on gasoline. Each engine gets its own specifications for fuel delivery, ignition and emissions, and both share the transmission, driveline, brake, suspension and body electrical procedures that make up the rest of the book.

Known issues on the 2009 Avalanche. Five recalls are recorded for this model year. Three describe an air bag inflator that can rupture during deployment and drive metal fragments at the occupants. A fourth involves the fuel system control module, whose sealant can separate from the housing and admit water, producing shorts or open circuits, a lit service engine lamp, stored trouble codes and hard starting. The fifth is the heated washer module that can ignite. Air bags take 47 of 96 complaints, and restraint, fuel control and body electrical diagnosis are all covered here.
