1999 Chevrolet Express 1500 Service and Repair Manual

This factory service and repair manual for the 1999 Chevrolet Express 1500 runs to three gasoline V-engines: the 4.3L V6 at 262 cubic inches, the 5.0L V8 at 305 and the 5.7L V8 at 350, all overhead-valve and naturally aspirated. The van itself stays simple, a three-door cargo body and a three-door passenger body offered as Base or LS. Specifications, torque values, wiring diagrams and diagnostics are laid out by system, so an oil pressure question and a lighting question are answered in different chapters.

Known issues on the 1999 Express 1500. One recall stands against this year, and it involves replacement oil filters sold for these engines: the affected parts may not seal properly, letting engine oil escape and, near hot surfaces, start a fire. Owner complaints number only four, three of them on the electrical system and one on exterior lighting. Lubrication routing, oil pressure specifications and the circuits behind the lamps are exactly the ground this manual covers, with wiring diagrams for tracing a lighting fault and engine specifications for confirming pressures after any service.
