1999 Chevrolet Silverado 1500 Service and Repair Manual

This factory service and repair manual for the 1999 Chevrolet Silverado 1500 takes on three engines and three cab configurations, which makes it a wider job than the badge suggests. Two overhead-valve V8s, of 5.3 and 4.8 liters, sit alongside a 4.3-liter V6, all naturally aspirated and gasoline-fueled. The bodies run from a two-door standard cab through two- and three-door extended cabs, and the Base, LS and LT trims mean the wiring diagrams and body sections branch where the engine sections do not.

Known issues on the 1999 Silverado 1500. Two recalls reach this model year, and both involve replacement filters rather than parts fitted at the factory. One covers oil filters that may not seal properly, letting engine oil escape where it can find an ignition source. The other covers fuel filters with the same weakness at the connection, where a leak in the fuel line carries the same risk. Owner complaints total 599 and lean hard on the service brakes at 349, followed by 39 on the structure and 29 on the suspension — systems this manual specifies and diagnoses in full.
