1988 Chevrolet R10 Suburban Service and Repair Manual
This factory service and repair manual for the 1988 Chevrolet R10 Suburban narrows the choice to two engines, one gasoline and one diesel: the 5.7L V8 of 350 cubic inches and the 6.2L V8 of 379, both overhead-valve and both naturally aspirated. One body is listed, the four-door sport utility, and two trims, Scottsdale and Silverado. The split between fuels is the main division in the manual — the diesel gets its own diagnostics and specifications, while everything from the flywheel back is shared.

Known issues on the 1988 R10 Suburban. The federal record shows no recalls and no owner complaints for this year. That absence puts the weight on routine service, which for a heavy wagon of this age means the brakes, the cooling system, the axles and the wiring more than anything exotic. All of it is documented: overhaul and adjustment procedures for both V8s, transmission and axle work, brake and steering service, suspension specifications, and wiring diagrams to work a fault back to its source rather than replacing parts on a hunch.
