- Socket set
- Torque wrench
- Screwdrivers
- Battery terminal cleaner

2. Battery Inspection and Replacement

Inspect Battery Terminals
- Clean any corrosion using a battery terminal cleaner.
- Ensure connections are tight and secure.
Battery Replacement (if required)
- If the battery fails the load test or has low voltage, replace it.
- Remove the old battery by loosening the terminal clamps (negative first, then positive).
- Lift the battery out of the tray and replace it with a new battery of the same specifications.
- Reconnect the terminals (positive first, then negative).
- Torque the terminal bolts to manufacturer specifications (generally around 10-15 ft-lbs).

3. Starter Motor Inspection and Replacement

Remove Starter Motor

- Remove any components obstructing access to the starter motor (e.g., air intake duct).
- Unplug the electrical connector from the starter.
- Remove the bolts securing the starter motor to the engine block (typically 2-3 bolts).
- Carefully extract the starter motor from its position.
Install New Starter Motor
- Position the new starter motor in place.
- Secure it with bolts and torque them to manufacturer specifications.
- Reconnect the electrical connector.

4. Finalize and Test

Reconnect Battery
- Reconnect the negative terminal of the battery.
Test the System
- Attempt to start the vehicle to check if the issue is resolved.
