1983 Chevrolet G30 Service and Repair Manual

This factory service and repair manual for the 1983 Chevrolet G30 has five trims to keep straight, Beauville, Bonaventure, Chevy, Hi-Cube and Sportvan, across a passenger van, a cargo van and two cutaway bodies. Three engines are covered, and they are far apart in character: a 4.1L inline-six of 250 cubic inches, a 5.7L gasoline V8 of 350 and a 6.2L diesel V8 of 379, all overhead-valve and naturally aspirated. The diesel's service data is kept separate from the gasoline material throughout.

Known issues on the 1983 G30. Both items on this year's federal record concern parts bolted on rather than built in: a platform trailer hitch made from something other than pure steel, which will not hold up under normal towing stress, and a replacement oil filter that seals poorly and can let the engine bleed off its oil, with fire the possible result. Owner complaints number just one, and it concerns the tires. Hitch and frame fastener torque values, engine lubrication procedures and wheel-end service data all sit in this manual, along with the diagnostics for the systems they belong to.
