1987 GMC R1500 Suburban Service and Repair Manual
This factory service and repair manual for the 1987 GMC R1500 Suburban is written for the four-door sport utility in Base, High Sierra and Sierra Classic trim, with three overhead-valve engines behind it: 5.0L and 5.7L gasoline V8s of 305 and 350 cubic inches, and a naturally aspirated 6.2L diesel V8 of 379 cubic inches. A Suburban carries a full passenger interior on truck running gear, and the manual documents both halves of that, giving procedures, specifications, torque values, wiring diagrams and diagnostics for each system.
