1999 Chevrolet C3500HD Service and Repair Manual
This factory service and repair manual for the 1999 Chevrolet C3500HD treats the truck as the two-engine, two-body chassis it is: the 6.5-liter turbocharged diesel of 395 cubic inches or the 7.4-liter 454 gasoline V8, in a two-door conventional cab and chassis or a four-door crew cab and chassis, Base trim throughout. The value of a single trim level is that equipment lists barely branch, so a wiring diagram or a torque figure applies to nearly every truck built that year.

Known issues on the 1999 C3500HD. Four owner complaints are recorded for the 1999 chassis — one on the service brakes, one on the electrical system and one on the fuel system. Thin numbers for a low-volume truck, but each lands on a system this manual documents in depth. Brake coverage runs through hydraulic components, adjustment and diagnosis; the electrical sections give wiring diagrams, connector views, ground points and circuit testing; and fuel coverage takes in tank, lines and filtration and, on the turbodiesel, injection pump and glow plug service with the specifications each step needs.
