Three months ago, I received by 2010 SE. Although I've been driving for some 30 years and know the very basics of how cars operate, I have never actually performed more than routine elementary maintenence on my car (oil/filter, tire change, battery/air filter change). I'd like to learn more on my own by reading a comprehensive textbook which takes me from the very basics through a fairly in-depth knowledge of car function, diagnosis, and repair. I never intend doing my own repairs but I would enjoy knowing more about car functioning and how my mechanic would diagnose and repair common problems. A book with a great many diagrams and photographs is necessary. Through amazon.com I have it pretty well down to 2 books. Either AUTOMOTIVE TECJNOLOGY: A SYSTEMS APPROACH by Erjavec or AUTOMOTIVE TECHNOLOGY: PRINCIPLES, DIAGNOSIS, SERVICE by Halderman. I can review either copy well since amazon shows only a few pages.I wounder if the group could comment on which book might be most helpful. Thanx.
