How to install battery in new battery
Place the DeVille in "Park" and allow the vehicle components to cool for a half hour.
Locate the battery under the hood of the DeVille. The battery tray is located on the driver side of the Cadillac. Locate the strap securing the battery to the battery tray and unbuckle the strap.
Disconnect the negative cable using a combination wrench. The negative cable is the black cable. Place the cable to the side. Disconnect the positive cable next, which is the red cable, and place it to the side. The battery can now be removed. Lift the battery off of the battery tray, carefully. Dispose of the battery per local regulations.
Use a wire brush and clean rag to clear away debris and dirt on the battery tray to ensure a clean connection.
Install the replacement battery by placing it on the battery tray. Buckle the battery tray harness around the battery. Reconnect the red cable, followed by the black cable, using the combination wrench. Close the hood of the DeVille.
