Before you begin, you will need to gather the following tools and materials:
* A new battery (the correct size for your vehicle)
* A wrench set
* A screwdriver
* Safety glasses
1. Open the hood of your vehicle.
Locate the release latch for the hood, usually located inside the vehicle near the driver's seat. Pull the latch to release the hood, then lift it up and prop it open with the support rod.
2. Disconnect the negative battery terminal.
The negative terminal is usually marked with a "-" sign. Use a wrench to loosen the nut that holds the negative terminal cable in place, then remove the cable from the battery.
3. Disconnect the positive battery terminal.
The positive terminal is usually marked with a "+" sign. Use a wrench to loosen the nut that holds the positive terminal cable in place, then remove the cable from the battery.
4. Remove the old battery.
Once the battery cables are disconnected, you can remove the old battery from the vehicle. Be careful not to drop the battery, as it is heavy.
5. Clean the battery tray.
Use a damp cloth to clean the battery tray, removing any dirt or debris.
6. Install the new battery.
Place the new battery in the battery tray, making sure that the positive terminal is facing the positive terminal on the battery.
7. Connect the positive battery terminal.
Use a wrench to tighten the nut that holds the positive terminal cable in place.
8. Connect the negative battery terminal.
Use a wrench to tighten the nut that holds the negative terminal cable in place.
9. Close the hood of your vehicle.
Lower the hood and let it go. The hood should latch closed automatically.
That's it! You have now successfully changed the battery in your 2002 Impala.
