1987 Chevrolet G20 Service and Repair Manual
This factory service and repair manual for the 1987 Chevrolet G20 addresses a three-body range, extended passenger van, standard cargo van and extended cargo van, in Beauville, Chevy and Sportvan trim. Four naturally aspirated overhead-valve engines are documented: the 4.3L V6 of 262 cubic inches, the 5.0L V8 of 305, the 5.7L V8 of 350 and the 6.2L diesel V8 of 379. Because the same shell takes both gasoline and diesel power, the fuel, exhaust and cooling sections branch by engine while the body procedures stay common.

Known issues on the 1987 G20. Three recalls sit on this year's federal record, and two of them are about fuel escaping. Replacement fuel filters can seal poorly at the connection and weep gasoline, which near an ignition source becomes a fire. The lower fuel tank filler pipe can carry small holes at its spot welds and spill fuel during refueling or while turning. The third involves oil filters that lose their seal and drain the engine. Ten complaints are recorded, led by two on the steering and two on the structure, and steering linkage and fuel system service are both covered here.
