A great question my friend. First of all, only the correct battery should be used. There is possibly a replacement battery from Exide or Interstate, they are acceptable. The battery is located in the spare tire well, remove the carpet and floor board. Remove the battery, negative terminal first, then the mount at the bottom has a 10mm bolt head, get it out and pull the old battery. A battery terminal cleaner is a good idea to get clean connections, or a wire brush to clean any oxidation from the new terminals and from inside the battery leads. Install and secure the bottom mount, then the positive cable and last the negative cable. Reinstall the carpet and reset the clock and you are good to go.
