The books......
Which is better depends on you and your level of experiance. How dirty do you want to get your knuckles?
The Haynes manual is designed for the simple do it yourselfer. It has some good information, just not to detealed. It is written on about a 4th grade level so it is easy to understand. Available at Autozone.
The Chiltons manuel is a more detailed version of the Haynes. Written on about an 8th grade level. Most novice mechanic types preferred the Haynes beacuse it was easier to read. I grew up using this manual and loved it. Available at O'rileys?
The Factory books. The best most detailed information you can get. Will tell you everything and also a lot you did not want to know. The books themselves are expensive, almost double or triple the cost of Haynes, unless you find them on e-bay as mentioned. Then you can get a deal.
So you have 3 flavors to choose from, pick the one that suites you best.
