2008 Chevrolet Silverado 3500 Service and Repair Manual

This factory service and repair manual for the 2008 Chevrolet Silverado 3500 is built around the 6.0L OHV V8, a naturally aspirated 364-cubic-inch gasoline engine, in a two-door standard cab pickup offered in Base trim. A single powertrain and a single cab keep the material tight: engine, transmission and driveline procedures point at one configuration, and the wiring diagrams, torque values and diagnostic charts describe the body and electrical systems as this truck was actually built rather than as a range of options.

Engines covered

• 6.0L V8 (364 cu in) — OHV, naturally aspirated, gasoline

Known issues on the 2008 Silverado 3500. Two recalls appear on the federal record for this year. One concerns a heated washer fluid module whose circuit can misbehave, disturbing other electrical features and producing an odor or smoke as a fire builds. The other covers replacement headlamps sold without the amber side reflex reflector, which leaves the truck harder to see from the side at night. Owners have logged 1,076 complaints, heavily weighted toward air bags at 630, with the electrical system at 122 and structure at 39 — restraint and body electrical diagnostics both sit in this manual.
