Reading 'Auto Fundamentals' is like taking a college Auto Tech class at your own leasure! Pretty much every question you have about the fundamental automotive systems WILL be answered by the time you finish this textbook. This is an absolute must-read for anyone looking to get into an automotive field, no matter what branch. Plenty of pictures (with thier own accompanying explanations) are placed throughout the book to give you plenty of visual aides to go along with the text. Although this is an excellent read, there are a few parts of the book that can overwhelm you (eg. automatic transmissions/transaxles and power steering systems we're so over my head I had to skip those chapters). The author goes into extreme detail at the beginning of the book, but that detail kind of tapers off near the end. Not so much that you won't be able to comprehend what your reading, but enough that it may get a little frustrating to read. I'm still giving this 5 stars though, it more than deserves it for it's wide variety of content and (for the most part) clarity.
