I'm not sure if everybody know this but on Autozone's website they have a vehicle repair guide. If you click on shopping, then you pick the make, model, and year of your car, and then if you look to the right of current vehicle (should be below the autozone logo) they have a link that says vehicle repair guide that has a lot of information.
