How to Replace the Battery in My Cadillac CTS
- 1). Open the hood to access the battery. The battery is located on the passenger side of the engine compartment in the rear by the firewall. The battery is stored in a black housing.
- 2). Unbolt the positive and negative terminals from the battery with a socket wrench. Pull the cables away from the terminals and each other.
- 3). Open the housing by lifting the tab on the front to access the top of the battery. This will expose the top of the battery.
- 4). Pull the battery out of the casing. Place it to the side. Place the new battery in the casing.
- 5). Close the top by pulling the tab over to the front. It will lock in place.
- 6). Bolt the positive cable to the terminal indicated by a "+" symbol above it. Bolt the negative terminal to the remaining terminal.
