This factory information shows you how to repair your vehicle. With step-by-step instructions, clear pictures, exploded view illustrations, schematics, and specifications, you will have the information you need to get your project on the road and keep it there. Since 1989 trucks were similar to 1988 models, GMC did not print a new book for 1989, and continued to use this manual for repair. If you have a 1990 model, you'll need this book plus the 1990 supplement. Buy now to own the best manual for your vehicle.
Why buy a factory manual?
