1. Gather Your Supplies:
* New battery: Make sure you get the correct battery size and type for your Aurora. Check your owner's manual or the sticker on your old battery for this information. Auto parts stores can help you find the right one.
* Wrench (likely 10mm or 13mm): You'll need this to loosen the battery terminal clamps. A socket wrench will be faster and easier.
* Safety Glasses: Protect your eyes from acid splashes.
* Gloves (optional but recommended): Protect your hands from battery acid.
* Baking soda and water mixture: In case of battery acid spills.
* Wire brush (optional): To clean battery terminals.
2. Safety First:
* Disconnect the negative terminal first: Use your wrench to loosen and remove the nut/bolt on the negative (-) terminal (usually black). Set the cable aside, making sure it doesn't touch any metal parts of the car.
* Disconnect the positive terminal second: Loosen and remove the nut/bolt on the positive (+) terminal (usually red). Set this cable aside as well.
3. Remove the Old Battery:
* Locate the battery hold-down clamp: This is usually a metal clamp or bracket securing the battery in place.
* Remove the hold-down clamp: This might involve loosening a bolt or two. The method will vary slightly depending on your specific Aurora model.
* Lift out the old battery: Carefully lift the battery out of the battery tray. It might be heavy, so be careful not to strain yourself.
4. Install the New Battery:
* Inspect the new battery: Make sure it's not damaged and the terminals are clean.
* Install the new battery: Carefully place the new battery into the battery tray.
* Secure the battery with the hold-down clamp: Tighten the clamp securely.
5. Connect the Terminals:
* Connect the positive (+) terminal first: Attach the positive cable to the positive terminal and tighten the nut/bolt securely.
* Connect the negative (-) terminal second: Attach the negative cable to the negative terminal and tighten the nut/bolt securely.
6. Clean Up:
* Dispose of the old battery properly: Take it to a local auto parts store or recycling center. Do not throw it in the trash.
* Clean any battery acid spills immediately: Neutralize any spills with baking soda and water.
7. Check your work:
* Start your car. Everything should function normally.
Important Notes:
* Consult your owner's manual: This guide provides general instructions. Your owner's manual may have specific details relevant to your 2002 Oldsmobile Aurora.
* If you're uncomfortable doing this yourself, take your car to a qualified mechanic: Battery replacement is generally safe, but if you are unsure about any step, it's best to seek professional help.
By following these steps carefully, you should be able to successfully change the battery in your 2002 Oldsmobile Aurora. Remember safety first!
