Solution

1. Preparation

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

2. Battery Inspection and Replacement

Inspect Battery Terminals
- Clean any corrosion from battery terminals using a wire brush and baking soda solution.
- Ensure connections are tight and secure.
Test Battery Voltage
- Use a multimeter to check voltage; if below 12.4 volts, charge the battery.
Replace Battery (if necessary)
- Disconnect the positive terminal first, followed by the negative.
- Remove the battery hold-down clamp.
- Lift out the old battery and install the new one (ensure the same group size).
- Reconnect the positive terminal first, then the negative.

3. Starter Inspection

Access the Starter Motor
- Raise the vehicle safely using jack stands.
- Locate the starter motor (typically near the transmission).
Test Starter Motor
- Use a multimeter to check for voltage at the starter terminal when the key is turned.
- If no voltage is present, the starter may need replacement.
Replace Starter (if necessary)
- Disconnect wiring from the starter motor.
- Remove the starter mounting bolts (typically 2-3).
- Install the new starter and secure with bolts.
- Reconnect wiring.

4. Final Assembly

Reconnect the negative battery cable.
Lower the vehicle and ensure all tools are removed from the engine bay.
