1989 GMC K3500 Service and Repair Manual
This factory service and repair manual for the 1989 GMC K3500 is written around three overhead-valve engines and three body configurations. The engines are the 7.4L and 5.7L gasoline V8s and the 6.2L diesel V8; the bodies are the standard cab pickup, the extended cab pickup and the cab & chassis. Trim choices are Sierra, Sierra SLE and Sierra SLX. Because every engine is naturally aspirated, specifications and torque values stay comparable from one to the next, and only the diesel takes a separate fueling section.

Known issues on the 1989 K3500. Four recalls are attached to this model year, and three are worth stating plainly. Replacement oil filters sold for these trucks may not seal properly, so the engine can lose its oil and a fire can follow. The automatic transmission can force fluid out through the vent tube when it runs hotter than anticipated. And some trucks were supplied with incorrect instructions for adjusting the rear lap-shoulder belts, which can leave an occupant poorly restrained. One owner complaint, on the service brakes, is logged with NHTSA. Belt anchorage adjustment, transmission cooling checks and brake diagnostics each carry their own procedures and torque values in this manual.
