1982 Chevrolet G20 Service and Repair Manual

This factory service and repair manual for the 1982 Chevrolet G20 covers a van that left the plant with one of three overhead-valve engines: a 4.1L inline-six of 250 cubic inches, a 5.0L V8 of 305, or a 5.7L V8 of 350, all naturally aspirated and burning gasoline. Four body configurations sit on that hardware, passenger vans in standard and extended length and cargo vans in the same two lengths, while Beauville, Chevy and Sportvan make up the trims the procedures, specifications and wiring diagrams address.

Known issues on the 1982 G20. Three recalls appear on the federal record for this year. One involves a replacement oil filter that can seal inadequately and let the engine lose its oil, with a fire the possible outcome. Another concerns front safety belt anchorages that would not hold an occupant properly in a crash or sudden stop. The third is a differential pinion shaft whose locking screw can back out, damaging or jamming the gears and leaving the rear wheels without drive. A single complaint, against the seat belts, sits alongside them. Lubrication, restraint anchorage and rear axle work all carry procedures and torque values here.
