1989 GMC V1500 Suburban Service and Repair Manual
This factory service and repair manual for the 1989 GMC V1500 Suburban is written for the Base and Sierra Classic four-door sport utility with the same two overhead-valve V8s listed for the year, the 6.2L diesel and the 5.7L gasoline engine. Late-eighties full-size wagons are simple enough to repair and old enough that the original figures are hard to come by, which is what makes a factory book valuable: it states the published specifications, the torque values and the wiring layout rather than approximating them.
