- Clean any corrosion from the terminals using a wire brush and a mixture of baking soda and water.
- Ensure connections are tight and secure.
Test Battery Voltage
- Reconnect the battery and use a multimeter to check voltage.
- If voltage is below 12.4 volts, charge or replace the battery.
Replace Battery (if necessary)
- Remove the battery hold-down bracket using a socket set.
- Disconnect the positive terminal first, then the negative terminal.
- Remove the battery from the vehicle.
- Install the new battery by connecting the positive terminal first, followed by the negative terminal.
- Secure the battery with the hold-down bracket.

3. Starter Motor Inspection and Replacement

Locate the Starter Motor
- The starter motor is typically located near the bottom of the engine, near the transmission.
Remove the Starter Motor
