This beautiful reprint retains ALL of the content of the factory original, but because the publisher, Detroit Iron, uses a higher-quality paper than the super-thin original, the material has been split into two volumes in order to conveniently handle the thicker size.

What's in the books? Glad you asked. It's packed with over 1,300 pages of outstanding coverage of these great vehicles. In addition to the step-by-step text instructions, you'll find a massive number and variety of visual aids which complement those directions. Please scroll down to view a couple of sample pages which demonstrate some of the visual tools and how handily they work with the well-written information. Notice the Wheel Stud Replacement remove or disconnect instructions? There you'll see the "! Important" marker. It advises to "Support the caliper with a piece of wire to prevent damage to the brake line." It's tips like that which make this book so valuable. Don't learn the hard way. Observe the exploded view diagrams and how effectively they display all of the parts and fasteners involved and how they're supposed to be assembled. Having each item named/numbered delivers unrivaled clarity when paired with the instructions. You'll also see that, where applicable, the steps provide the factory-correct torque specifications to help you do the jobs safely and accurately.

To keep the popular "S" series fresh, Chevrolet spruced them up for '91, but they knew better than to mess with a good thing. To ensure yours is performing at its best, use the maintenance and repair details found in this professional guide.

This factory-written shop manual is perfect for service, repairs, restoration and rebuild projects. Clear illustrations and diagrams show exploded views, as well as component details, plus specifications, engine repair details, fuel systems and more.
