Solution

1. Preparation

Gather Tools: OBD-II scanner, multimeter, socket set, torque wrench, flashlight.
Safety Precautions: Ensure the vehicle is parked on a flat surface, and the engine is off and cool before beginning work.

2. Battery Inspection and Replacement

Check Battery Voltage: Use a multimeter to measure voltage; it should be around 12.6 volts for a fully charged battery.
Clean Terminals: If corrosion is present, clean battery terminals with a wire brush and a mixture of baking soda and water.
Replace Battery: If the battery voltage is low or the battery is more than three years old, replace it with a new one.
- Torque Specifications: Tighten the terminal connections to the manufacturer’s specified torque (usually around 10-15 Nm).

3. Engine Oil Change

Drain Old Oil: Use a socket set to remove the oil drain plug and let the old oil drain completely into a container.
Replace Oil Filter: Remove the old oil filter using an oil filter wrench, lubricate the rubber gasket of the new filter with fresh oil, and install it.
Add New Oil: Pour in the recommended type and amount of oil (check the owner's manual for specifications).
- Torque Specifications: Reinstall the drain plug and torque it to the manufacturer’s specifications (typically 20-25 Nm).

4. Belts and Pulleys Inspection/Replacement

Inspect Serpentine Belt: Look for signs of wear, such as cracks or fraying. If damaged, replace it.
Check Pulleys: Spin each pulley by hand to check for smooth operation; replace any that are stuck or wobbly.

5. Starter Motor Inspection/Replacement

Test Starter Motor: Use a multimeter to check for proper voltage at the starter when the ignition is turned on.
Replace Starter Motor: If faulty, disconnect the battery, remove the starter motor using the socket set, and install the new one, ensuring all connections are tight.
