This factory service and repair manual for the 1988 Chevrolet V30 covers LT and SS versions of the four-door sport utility with two engines on the list: a naturally aspirated 6.0L OHV V8 of 364 cubic inches and a naturally aspirated 4.2L DOHC inline-six of 256 cubic inches. A V8 and a straight six share almost nothing above the block, so ignition, fuel, accessory drive and cooling instructions are split, while the transmission, axle, brake and body procedures apply to both.

Known issues on the 1988 V30. Nothing has been recorded against this model year on the federal register — no recalls, no owner complaints. The manual's content therefore stands as the reference for ordinary repair: engine mechanical clearances and torque values for the V8 and the six, transmission and transfer case service, differential and wheel bearing specifications, brake hydraulic and friction data, steering and suspension adjustment figures, and the wiring diagrams that map the truck's circuits.
