How to Replace the Battery in a Toyota Corolla
Since 1968, the Toyota Corolla has been one of the most popular and reliable compact cars. This car will run smoothly for much more than 100,000 miles with proper maintenance. You should replace the battery if you see a white chalky substance on it, or it tests low on a battery-testing meter.
- Moderately Easy
- New 12-volt battery
- Battery terminal puller
- Wire brushes
- Socket wrench
- Old rags
Find the battery on the driver's side just behind the headlight.
Use a socket wrench to remove the metal battery holder.
Take off the cable ends from the battery terminals with a battery terminal puller. Remove the negative cable first.
Lift the battery out of the compartment. Safely dispose of used battery at an auto parts store, which will often take it as a trade-in, or bring it to a recycling center.
Use a wire brush to clean the tray that holds the battery. Wipe it off with a damp cloth and let it dry before replacing new battery.
Clean the insides of the connector cables with a pointed wire brush. Keep your gloves on at all times to avoid getting acid on your hands.
Place the new battery on the battery tray. Attach the correct cable on each terminal and tighten securely with pliers or socket wrench. Reattach the battery holder.
