Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park (or neutral) and the parking brake is engaged.
Disconnect the negative battery terminal to avoid electrical shock.

2. Battery Replacement

Tools Required: Socket set, wrench, battery terminal cleaner
1. Remove the negative battery terminal first, followed by the positive terminal.
2. Remove any brackets holding the battery in place.
3. Carefully lift out the old battery and place the new battery in the tray.
4. Reconnect the positive terminal first, then the negative terminal.
5. Secure the battery with brackets and clean any corrosion from terminals.

3. Starter Motor Inspection and Replacement

Tools Required: Socket set, torque wrench, multimeter
1. Locate the starter motor (typically near the transmission).
2. Disconnect the battery negative terminal again for safety.
3. Remove the electrical connections from the starter motor.
4. Unbolt the starter motor from its mount using the socket set.
5. Inspect the starter for signs of wear or damage; if faulty, replace it with a new unit.
