Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery:
- Clean the battery terminals using a wire brush.
- Ensure that connections are tight and secure.
Replace Battery (if necessary):
- Remove the battery hold-down bracket using a socket set.
- Disconnect the positive terminal followed by the negative terminal.
- Replace with a new battery of the same specifications (Group Size 65 typically).
- Reconnect terminals, starting with the positive, then negative.
- Secure the battery with the hold-down bracket.

3. Starter Inspection and Replacement

Remove Starter:
- Disconnect the negative battery terminal again.
- Locate the starter motor, typically mounted on the engine block.
- Remove any covers or shields obstructing access to the starter.
- Disconnect the electrical connectors from the starter.
- Remove the mounting bolts using a socket set.
- Carefully remove the starter from its location.
Replace Starter (if necessary):
- Position the new starter in place.
- Secure with the mounting bolts to the specified torque (usually around 30-40 ft-lbs).
- Reconnect the electrical connectors to the starter.
- Reinstall any covers or shields removed earlier.

4. Final Checks

Reconnect the negative battery terminal.
Ensure all tools are removed from the engine bay.
Start the vehicle to verify the repair.
