1983 GMC K1500 Suburban Service and Repair Manual
This factory service and repair manual for the 1983 GMC K1500 Suburban covers two engines in one body. The engines are the 6.2L diesel V8 and the 5.7L gasoline V8, both overhead-valve and naturally aspirated; the body is the 4-door sport utility, offered in Base, High Sierra and Sierra Classic trim. Diesel and gasoline service diverge in fuel delivery, starting and diagnosis, and the manual keeps those apart while treating the shared driveline, chassis, brake, electrical and body systems once, with full procedures and torque values.

Known issues on the 1983 K1500 Suburban. Nothing is on the federal record for this model year: no recalls, and no owner complaints logged with NHTSA. That leaves the manual's own coverage as the point of it, and there is plenty to work with, from overhaul specifications and clearances for the diesel and gasoline V8s to transmission and axle procedures, steering and brake adjustment, heater and air conditioning service, and the wiring diagrams and diagnostic charts that go with the body and chassis circuits.
