How To Replace 2003 Pontiac Grand Prix Battery

Unread post by vic » Tue Nov 27, 2012 12:54 pm

Can someone please give me detailed instructions on how to replace the battery to my 2003 Pontiac Grand Prix GTP?
I saw a video online, but they did not use a model for the entire video.

Replacing the battery is fairly simple on your Pontiac. There is a crossbar going from the right fender area to the core support, that needs to be removed and is just three 13mm bolts. After that, disconnect the battery cables and remove the battery hold down which is another 13mm bolt.

There may be a wiring harness that needs pulled out of the way, and you may want to remove the two 10mm nuts holding the fuse box assembly down and have a helping hand pull up on that while you lift the battery up. Easy!

Reverse the instructions for installation, done!
