Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Battery Inspection and Replacement

Inspect the Battery:
- Remove the battery terminals and clean any corrosion with a wire brush.
- Test the battery with a multimeter; if the voltage is below 12.4V, proceed to replace it.
Replace the Battery (if required):
- Remove the battery using a socket set.
- Install the new battery, ensuring it is secured properly.
- Reconnect the positive terminal first, followed by the negative terminal.

3. Engine Oil Change (if necessary)

Check Oil Viscosity:
- Remove the dipstick and check the oil thickness.
- If the oil is too thick for cold conditions, drain and replace it with the appropriate winter-grade oil (e.g., 0W-30 or 5W-30).
Change Oil:
- Drain the old oil using an oil catch pan.
- Replace the oil filter using an oil filter wrench.
- Refill the engine with the new oil through the oil filler cap.

4. Starter Motor Inspection

Check Starter Operation:
- Inspect the starter motor and solenoid for any signs of wear or failure.
- If faulty, remove the starter using a socket set and replace it with a new unit.
