1984 GMC C1500 Suburban Service and Repair Manual
This factory service and repair manual for the 1984 GMC C1500 Suburban documents a four-door sport utility offered in three trims, Base, High Sierra and Sierra Classic, with a choice of three engines. Two are gasoline V8s of 5.0 and 5.7 liters; the third is the 6.2L diesel V8. All are naturally aspirated overhead-valve designs. The diesel changes the service picture considerably, bringing injection timing, glow plug and fuel supply procedures that have no equivalent on the gasoline side, and the manual keeps those sections apart.
