Automotive Mechanics Volume I (Part 1 to part 6)
(Missing chap 14, 16-22, 26, 27. 29 -31, 34)
Automotive Mechanics: Volume I
The seventh edition of Automotive Mechanics has been completely revised. It is a
comprehensive automotive text, consisting of two volumes that relate to
passenger and light commercial vehicles. The text covers principles, applications
and general servicing requirements.
Volume 1 commences with an introduction to motor vehicles which includes
workshop practices and the use of tools. It then covers engine operation; engine
systems; manual transmissions; drives; running gear; suspension; steering and
general maintenance requirements. It concludes with electrical fundamentals and
basic electrical systems.
Volume 2 covers engine construction and overhaul; fuel and engine
management; diesel engines; automatic transmissions; four-wheel drive; engine
electrical systems; body electrics and also a number of vehicle safety, security
and convenience systems.
Volume 1, with its early introductory chapters, is useful for the earlier stages of a
course, while Volume 2, with some of the more advanced material, is suitable for
some of the later stages. However, each volume is complete with all related
material for its topics - principles, applications, construction of components and
basic servicing requirements are all located conveniently within the same
volume.
Both books are easy to use. There is a brief contents list as well as a detailed
contents list at the front of each volume. Also, each volume is divided into a
number of parts with a contents list at the start of each part. Further, the main
topics for each chapter are shown at the start of the chapter. A glossary and a
comprehensive index are provided for each volume. All these features enable
information to be quickly located.
These two volumes of Automotive Mechanics provide a valuable resource for all
automotive students. They would also have an important place in any automotive
technician's library. While Automotive Mechanics does not attempt to replace

vehicle manufacturers' manuals, these volumes do provide a general resource
that complement them.
