1987 GMC V1500 Suburban Service and Repair Manual

This factory service and repair manual for the 1987 GMC V1500 Suburban covers the four-door sport utility with a choice of two overhead-valve V8s: the naturally aspirated 6.2L diesel of 379 cubic inches and the 5.7L gasoline engine of 350. Base, High Sierra and Sierra Classic trims are listed. The diesel and the gasoline V8 share a body and a chassis but very little else in service terms, so injection, glow, cooling and charging coverage is engine-specific while the driveline, brake and body sections apply to both.
