Chilton? Haynes?
Both of these company's have consumer and professional grade service manuals. The consumer grade are the ones that are full of misinformation and poor editing. A repair shop will always have the professional series of service manuals and the cost is well over $200.00. Like most things, you get what you pay for.
You can also sign up for on-line service info on vehicles. A lot of service shops are doing the on-line thing, which is a fee for so long of a time; month, year, and so on. The on-line service has a consumer section in that you can pick one vehicle to get info on which is cheaper. AllData is one company and here is a link:
