Replace battery 2003 CTS

To replace the battery in a 2003 Cadillac CTS, is is simply a matter of removing the old and putting in the new, or are there a bunch of computer and other settings that need to be renewed? If so, do those settings have to be renewed at the dealership or can they be renewed by the owner?
Much obliged for any comments.

You will be fine replacing the batt. The only code that you will need is for the radio if it is stock. You do not need to worry about the computer it will be fine. You can get the code here at this site though.

How to install the front bumpers air deflector on a 2003 cadillac cts


If you have the new deflector already, go to your local auto parts store and get 8 - 10 plastic retainers. Pry the old ones open and pop them out. Put the new deflector in place and "pop" in the new retainers. Did mine in about 5 minutes. Don't get the retainers at the dealer. They are about 3 bucks a piece. At O'Reilley's they are 2 for a buck (I Think, It's been a while.) This is an easy fix that will really improve the looks, and resale value, of your CTS. Hope this helps.8_22_2012_1_19_36_am.jpg

How to replace Support Cylinder on 2003 cts trunk


Go to Car Quest or Napa parts store and have them order the new supports. There are two different lengths- be sure to measure the old ones. Use a flat screwdriver to take the old ones off following the directions on the new package. The new ones basically snap back on. Pay attention as to the top and bottom before you remove the old ones.
