This product is intended to help you learn more about the inner workings of your vehicle while saving you money on its upkeep and operation.
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. Information on procedures such as rebuilding a differential is not included in this material, 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, give you personal satisfaction and help you avoid expensive problems.
In this case, no tools at all are required.
