GM Full-Size Trucks 1980-1987 Repair Guide



This information guide, for 1 /2, 3 /4 and 1 ton Chevrolet and GMC Pick-Ups and Suburbans, is intended to help you learn more about the inner workings of your vehicle while saving you money on its upkeep and operation.

The beginning of the guide will likely be referred to the most, since that is where you will find information for maintenance and tune-up. The other sections deal with the more complex systems of your vehicle. Systems (from engine through brakes) are covered to the extent that the average do-it-yourselfer can attempt. This information will not explain such things as rebuilding a differential because the expertise required and the special tools necessary make this uneconomical. It will, however, give you detailed instructions to help you change your own brake pads and shoes, replace spark plugs, and perform many more jobs that can save you money and help avoid expensive problems.

A secondary purpose of this guide is a reference for owners who want to understand their vehicle and/or their mechanics better.
