- Use a socket wrench to disconnect the negative terminal first, then the positive terminal.
Clean Battery Terminals:
- Use a wire brush to remove corrosion from the terminals and battery posts.
Test the Battery:
- Connect the multimeter to the battery terminals to check voltage. If it’s below 12.4 volts, proceed to the next step.
Replace the Battery (if necessary):
- Remove the battery hold-down bracket using a socket wrench.
- Lift the old battery out and replace it with a new battery of the same specifications.
- Reinstall the hold-down bracket and connect the positive terminal first, then the negative terminal.

3. Starter Motor Inspection and Replacement

Locate the Starter Motor:
- It is typically located near the transmission on the passenger side.
Remove Electrical Connections:
- Disconnect the wiring harness and the positive cable from the starter motor using a socket wrench.
Remove Starter Motor:
- Unbolt the starter motor from its mounting using the appropriate socket size.
