Solution

1. Preparation

Gather necessary tools and parts for the repair.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Remove Battery Terminals
- Use a socket wrench to detach the negative terminal first, followed by the positive terminal.
Inspect Battery Condition
- Check for any physical damage or swelling on the battery casing.
- Clean any corrosion on the terminals using a mixture of baking soda and water.
Test Battery Voltage
- Connect a multimeter to the battery terminals. If the voltage is below 12.4V, charge or replace the battery.
Install New Battery (if applicable)
- Position the new battery in the tray, secure it with the hold-down bracket.
- Reconnect the positive terminal first, followed by the negative terminal.

3. Starter Motor Inspection and Testing

Access Starter Motor
- Raise the vehicle using a jack and secure it with jack stands.
- Locate the starter motor; it is generally found on the transmission bell housing.
Check Starter Connections
- Inspect the wiring and connections to the starter motor for any damage or corrosion.
- Tighten any loose connections.
Test Starter Operation
- Using jumper cables, connect the starter directly to the battery to see if it engages. If it clicks but does not turn, the starter may need replacement.

4. Replace Starter Motor (if necessary)

Remove Starter Motor
- Disconnect the wiring harness from the starter.
- Use a socket set to remove the bolts securing the starter motor to the engine.
Install New Starter Motor
- Position the new starter motor in place and secure it with bolts to the engine.
- Reconnect the wiring harness ensuring all connections are secure.
