The introductory part of this repair guide for the Buick LeSabre, Oldsmobile Delta 88/Eighty Eight and Pontiac Bonneville 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 information 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. Operating systems from engine through brakes are covered to the extent that the average do-it-yourselfer becomes mechanically involved. This information will not explain such things as rebuilding a differential for the simple reason that the expertise required and the investment in special tools make this task 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, give you personal satisfaction and help you avoid expensive problems.
A secondary purpose of this information is a reference for owners who want to understand their vehicle and/or their mechanics better. In this case, no tools at all are required.
