Service manuals have been helping people work on and/or fix automobiles for many years! Seasoned veterans (dealerships and mechanics) and ordinary people (like me) use service manuals on a regular basis! I used to have no idea how to change my own oil, but with a service manual handy, I was able to learn with no problems at all! All mechanics who you would normally pay to work on your car or truck uses a service manual to do the job! Everyone has to learn somewhere, and that place is the service manual! Don't pay inflated prices for work when you can easily do it yourself!
