GMC

We cover 14 GMC models, built for work and towing. They include the Sierra pickup and Savana van (2000 to 2023), the Yukon, Acadia, Canyon and Terrain, the electric Hummer EV, and older trucks like the Jimmy, Sonoma, Envoy and TopKick.

These are GM factory service manuals with the procedures, specifications and wiring diagrams dealer technicians use. Many GMC trucks share parts with Chevrolet, but trims, engines and equipment differ, so choose the exact GMC model and year.
