This factory service and repair manual for the 1982 GMC B6000 covers a cab forward school bus chassis, listed under the single designation B6P042, with an unusually broad engine choice for one body: three gasoline V8s of 5.7L, 6.0L and 7.0L, and two 8.2L V8 diesels, one turbocharged and one naturally aspirated. Gasoline and diesel want different diagnostics, so the manual keeps their fuel, ignition and injection material apart while sharing the chassis and body sections.
