My suggestion is to get a repair manual if your going to work on your own vehicle, and it's easy and inexpensive to get a high quality repair manual. To be better prepared, read up on the job you're about to perform, it will show you component locations and what special tools you'll need. Try and you can have one in minutes, for less than $30.00.
