Solution

1. Preparation

Tools Required:
- Socket set
- Screwdrivers
- OBD-II scanner
- Stethoscope (optional for noise isolation)
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect Serpentine Belt

Locate the serpentine belt and visually inspect it for cracks or fraying.
If damaged, remove the belt by loosening the tensioner pulley using a socket wrench.
Replace with a new serpentine belt, ensuring proper routing, and tighten the tensioner back.

3. Check Engine Oil

Remove the dipstick and check the oil level; add oil if low.
If the oil is dirty or has not been changed per the maintenance schedule, perform an oil change:
- Drain the old oil using a wrench to remove the oil drain plug.
- Replace the oil filter using an oil filter wrench.
- Refill the engine with new oil as specified in the owner's manual.

4. Inspect Transmission Fluid (if applicable)

Check the transmission fluid level using the dipstick; add fluid if low.
If fluid is dark or burnt, consider replacing the transmission fluid and filter.

5. Examine Drivetrain Components

Inspect CV joints for tears or leaks; replace any damaged components.
Check the differential for proper lubrication; add fluid if necessary.
Look for any play or unusual wear in the drivetrain components.
