Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park (automatic) or neutral (manual) with the parking brake engaged.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection and Replacement

Inspect Battery Condition
- Check for corrosion around terminals; clean if necessary using a mixture of baking soda and water.
- If the battery voltage is below 12.4 volts, proceed to replace the battery.
Replace Battery
- Remove the negative terminal first, followed by the positive terminal.
- Unscrew any hold-down clamps or brackets.
- Lift out the old battery and install the new battery in reverse order, connecting the positive terminal first, then the negative terminal.

3. Starter Inspection and Replacement

Remove Starter
- Disconnect the battery terminals again for safety.
- Locate the starter, typically found on the lower side of the engine near the transmission.
- Remove any heat shields or covers if necessary.
- Unbolt the starter from its mounting.
- Disconnect the electrical connectors attached to the starter.
Install New Starter
- Position the new starter in place and secure it with bolts to the mounting location.
- Reconnect the electrical connectors ensuring a secure fit.
- Reinstall any heat shields or covers removed earlier.

4. Final Checks

Reconnect the negative battery terminal.
Ensure all tools are removed from the engine bay.
Attempt to start the vehicle.
