Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery:
- Check for any damage or leaks.
- Clean the terminals using a battery terminal cleaner.
Replace Battery (if necessary):
- Remove the positive terminal first, then the negative.
- Unbolt the battery hold-down bracket and remove the battery.
- Install the new battery, securing it with the hold-down bracket.
- Connect the negative terminal first, then the positive.

3. Starter Motor Inspection and Replacement

Remove the Starter Motor:
- Locate the starter motor (typically near the transmission).
- Disconnect the wiring harness and the main power cable.
- Remove the mounting bolts using a socket set.
- Carefully remove the starter motor from the vehicle.
Install New Starter Motor:
- Position the new starter motor in place.
- Secure it with mounting bolts to the manufacturer's torque specifications (usually around 15-25 lb-ft).
- Reconnect the power cable and wiring harness.

4. Final Checks

Reconnect the negative battery terminal.
Ensure all connections are secure and free from corrosion.
Perform a visual inspection of all components related to the starting system.
