Solution

1. Preparation

Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the battery to prevent any electrical short circuits.
Gather necessary tools and parts.

2. Battery Replacement (if necessary)

Tools Required: Wrench set, multimeter, battery terminal cleaner.
Remove the negative (-) terminal from the battery first, followed by the positive (+) terminal.
Remove any brackets or hold-downs securing the battery.
Carefully lift the old battery out of the battery tray.
Install the new battery by placing it in the tray and securing it with brackets.
Connect the positive (+) terminal first, then the negative (-) terminal.
Ensure all connections are tight and clean.

3. Starter Replacement (if necessary)

Tools Required: Socket set, torque wrench, ratchet.
Locate the starter motor, usually found near the engine block.
Disconnect the battery again before proceeding.
Remove any components obstructing access to the starter (e.g., air intake duct).
Unplug the electrical connectors from the starter.
Remove the mounting bolts holding the starter in place using a socket set.
Carefully remove the starter from its position.
Install the new starter by reversing the removal steps, ensuring proper alignment and tightness of bolts (typically torque to manufacturer specifications).
