1999 GMC C3500HD Service and Repair Manual
This factory service and repair manual for the 1999 GMC C3500HD lists three engines for a chassis offered in two forms. The turbocharged 6.5L diesel V8 heads the list, followed by the naturally aspirated 7.4L and 5.7L gasoline V8s; the bodies are the two-door conventional cab and chassis and the four-door crew cab and chassis, both in Base trim. Coverage follows the truck's systems rather than its options, so a technician looking for a torque value, a wiring diagram or a diagnostic sequence finds it under the system it belongs to.

Known issues on the 1999 C3500HD. Two owner complaints are logged with NHTSA against this model year, one on the service brakes and one on the tires. Both concern the part of a heavy chassis that carries and stops the load, and both are ordinary places for wear to show. The manual covers brake hydraulics, friction hardware, the parking brake and their adjustment and bleeding procedures, together with wheel and hub service, wear limits, fastener torque values and the diagnostics used to trace a pull, a vibration or a long pedal.
