Fundamentals of Automotive Technology: Principles and Practice 2nd Edition
Genres: Engineering & Transportation
Book Preface
Note to Students
This book was created to help you on your path to a career in the transportation industry. Employability basics covered early in the text will help you get and keep a job in the field. Essential technical skills are built in cover to cover and are the core building blocks of an advanced technician’s skill set. This book also introduces “strategy-based diagnostics”, a method used to solve technical problems correctly on the first attempt. The text covers every task the industry standard recommends for technicians, and will help you on your path to a successful career.
As you navigate this textbook, ask yourself, “What does a technician need to know and be able to do at work?”
This book is set up to answer that question. Each chapter starts by listing the technicians’ tasks that are covered within the chapter. These are your objectives. Each chapter ends by reviewing those things a technician needs to know. The content of each chapter is written to explain each objective. As you study, continue to ask yourself that question. Gauge your progress by imagining yourself as the technician. Do you have the knowledge, and can you perform the tasks required at the beginning of each chapter? Combining your knowledge with hands-on experience is essential to becoming a Master Technician.
During your training, remember that the best thing you can do as a technician is learn to learn. This will serve you well because vehicles keep advancing, and good technicians never stop learning.
Stay curious. Ask questions. Practice your skills, and always remember that one of the best resources you have for learning is right there in your classroom . . . your instructor.
Best wishes and enjoy!

Early vehicles were very basic machines with engines that were started by manually operating a crank handle and required almost continual tinkering and maintenance. As vehicle technology developed over time, the maintenance requirements have evolved as well (FIGURE 1-1). Although early vehicles and today’s vehicles have some of the same basic systems—ignition, cooling, engine, drivetrain, suspension, and lubrication—the systems on modern vehicles are much more sophisticated and reliable. Modern vehicles travel much greater distances between maintenance appointments than their predecessors. For example, it is not unusual for a vehicle manufacturer to require maintenance at 7500- to 10,000-mile (12,000 to 16,000 km) intervals. And there is a push to extend maintenance intervals even further as new lubricants, materials, and machining processes are being developed. In fact, some manufacturers are predicting maintenance intervals of 25,000 miles (40,000 km) in the near future; in comparison, some earlier vehicles required maintenance every 1000 miles (1600 km).
Although maintenance requirements have decreased over time, the need for more substantial repairs has also decreased. It wasn’t very long ago that engines would last about 100,000 miles on average. Now they routinely last well over 200,000 miles. Better metals, better machining processes, and better lubricants all extend the life of vehicle components. That doesn’t mean that they don’t wear out or need to be replaced, they do—just not as often as in years past. At the same time, vehicles have many more safety and convenience systems and features, making them more complex. So that has increased the types of repairs that technicians must be able to perform. In fact, many systems are now electrically or electronically operated. So technicians must have a strong understanding of electrical/electronic theory to be able to diagnose virtually all of the systems on today’s vehicles.
