Replace Battery 2008 - 2013 Cadillac CTS

Have you got a weak or dead battery in your 2nd generation Cadillac CTS? Spoiler Alert! It's in the trunk. I'll show you how to get to the battery and swap it out quickly using just a few hand tools. Let's get busy!
Note: In the video I asked where this vacuum hose went. A viewer answered that it connects to a port on the battery.

the hose is a breather tube to let fumes escape outside vehicle there is a port on the battery for it

Ah, fantastic! Thanks! I just plugged it in. I'll pin this comment to the top and add the info into the description.

The loose hose you mentioned is actually a vent line for the battery. The top left of the battery has a little vent hole for the battery to breathe, and you hook it up on the left side of the top of the battery. There is usually a small little red plug that is in the new battery. Once you take that out, you can insert the breathing tube.

Thanks! I've got it plugged in now. I guess the previous battery had never been plugged in either.

Another good reason for owning an older vehicle. The auto companies seem to intentionally build in more complications with each passing year. My favorite thing about your car is the symbol on the rear, brother.

My wife loves Cadillacs. Not that I can afford to buy new ones but this CTS has been a good car for the last 8 years.

@@floridarusticrepairs The symbol on the back that I was referring to was the Fish. I was very happy to see it.

I always put a little grease on the terminals. Good job. Wonder what that vacuum hose was in the back. Thanks for sharing! 💯👍

[@floridarusticrepairs]

Thanks! I'm hoping someone can answer vacuum hose mystery that for me. It appears to go nowhere.

[@carlvarner709]

You are actually supposed to remove the ground cable first, then positive. And when you put the new battery back in, you should connect the positive first and the ground ground last.

[@floridarusticrepairs]

Interesting. I wonder what the ill effects are supposed to be from connecting ground and then positive. Thanks for the info!

[@xxOutkastedxx]

use a little coca cola or baking soda and water to nuetralize that acidic powder before breathing that crap in. and always remove path to ground first aka black first then red when removing and black last when installing.

[@floridarusticrepairs]

Thanks! I used battery terminal cleaner that i got at an estate sale. Seemed to work well enough.

[@adamspicer-qj7ff]

Can you assist me with where the 12V- teethers to the car.

[@floridarusticrepairs]

Under the hood, on the passenger side look for a red plastic cover with a "+" sign on it. This is how you would jump start the car. I hope this helps.

[@adamspicer-qj7ff]

@@floridarusticrepairs I am asking about the 12-. The ground cable. One end connects to the negative part on the battery and where does the other end bolt to the car? I have a NO CRANK NO START. AND I BEETLEJUICE MY BATTERY IS NOT GROUNDED CORRECTLY

[@floridarusticrepairs]

@@adamspicer-qj7ff I looked up the replacement part and it looks like the ground cable running from the battery is not very long. Under two feet. My guess is that it connects to the chassis in the trunk. the other thing to consider is that there are actually many grounding points and grounding wires on these cars so, even if it is a grounding issue it may not be the main cable. You should be able to test your theory by running a jumper cable from your negative terminal to any grounding spot on the car thereby creating a new ground. Good luck!

[@adamspicer-qj7ff]

Thank you sir. And I will do that with a jumper. I have to wait until the 1st to get it from the dealership

[@floridarusticrepairs]

@@adamspicer-qj7ff I'm glad I was able to help! Good luck with the repair.

[@user-rc5zb9qv3z]

I wonder who the idiot was that thought it was a good idea to put a battery in such an inaccessible location.

[@floridarusticrepairs]

lol. I'd guess it has to do with weight distribution. I think they could have deigned the surrounding enclosure better for sure.

[@guillermoavina2252]

This is not the same as the 2014 CTS

[@floridarusticrepairs]

Thanks for the info! I've changed the title and thumb. Much appreciated.
