This product is intended to help you learn more about the inner workings of your vehicle, 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.
In this case, no tools at all are required.
