Solution

1. Preparation

Gather necessary tools and parts before starting.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Inspect the Battery:
- Check for any visible damage or swelling.
- Clean the battery terminals using a wire brush and a solution of baking soda and water to remove corrosion.
Replace the Battery (if needed):
- Remove the battery hold-down clamp using a socket set.
- Disconnect the positive terminal first, followed by the negative terminal.
- Replace with a new battery, ensuring correct polarity.
- Reconnect the terminals, tightening securely.

3. Starter Motor Replacement

Remove the Starter:
- Locate the starter motor (usually near the transmission).
- Disconnect the electrical connectors from the starter.
- Remove the mounting bolts using a socket set.
- Carefully pull the starter out of its location.
Install the New Starter:
- Position the new starter motor in place.
- Secure it with the mounting bolts, tightening them to the manufacturer’s specifications (consult repair manual for torque values).
- Reconnect the electrical connectors.

4. Final Checks

Reconnect the negative battery terminal.
Start the engine to check for proper operation.
Ensure all electrical components function correctly after the repair.
