Solution

1. Preparation

Tools Required: Multimeter, socket set, wrench set, screwdriver set, wire brush, jumper wire.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Inspect Battery Condition
- Clean any corrosion from the terminals using a wire brush.
- Check the battery voltage again; if below 12.4 volts, proceed to replace the battery.
Disconnect and Remove Battery
- Disconnect the negative terminal first, followed by the positive terminal.
- Remove the battery hold-down clamp and lift the battery out.
Install New Battery
- Position the new battery in the tray.
- Connect the positive terminal first, then the negative terminal.
- Ensure terminals are tight to prevent poor connections.

3. Starter Inspection and Replacement

Locate the Starter
- Lift the vehicle using jack stands if necessary and locate the starter motor under the vehicle.
Remove Starter Motor
- Disconnect the electrical connections from the starter.
- Remove the mounting bolts securing the starter to the engine block.
- Carefully extract the starter from its position.
Install New Starter
- Position the new starter in place and secure it with the mounting bolts, tightening to manufacturer specifications (typically around 30-35 ft-lbs).
- Reconnect the electrical connections ensuring they are secure.
Reconnect Battery
- Connect the positive terminal first, then the negative terminal.
