1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is in park (automatic) or neutral (manual) with the parking brake engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Replacement

Tools Required:
- Wrench set
- Battery terminal cleaner
- Safety goggles
Remove the negative terminal first, followed by the positive terminal from the battery.
Remove any hold-down brackets securing the battery.
Lift the old battery out of the tray and place the new battery in the same position.
Secure the new battery with the hold-down brackets.
Connect the positive terminal first, followed by the negative terminal.
Clean any corrosion on terminals using a battery terminal cleaner.

3. Starter Replacement (if necessary)

Tools Required:
- Socket set
- Torque wrench
- Ratchet
Locate the starter motor (usually at the transmission bell housing).
Disconnect the battery again.
Remove electrical connections from the starter (noting their positions).
Remove the mounting bolts securing the starter motor.
Carefully extract the starter from its position.
Install the new starter by reversing the removal steps, ensuring all connections are secure.
Torque the mounting bolts to the manufacturer's specifications (typically 25-35 ft-lbs).
