Solution

1. Preparation

Gather tools such as a socket set, OBD-II scanner, and safety glasses.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Inspect and Replace Fluid

Coolant:
1. Open the hood and locate the coolant reservoir and radiator cap.
2. If low, add the appropriate coolant type (refer to owner's manual).
3. Check for leaks in hoses and connections; replace any damaged components.
Transmission Fluid:
1. Locate the transmission dipstick (if applicable).
2. Remove the dipstick and check fluid level; add fluid if necessary.
3. If fluid is burnt, drain the transmission and replace with new fluid.

3. Inspect and Replace Belts

Check the serpentine belt for cracks or fraying.
If damaged, remove the tensioner and replace with a new belt.
Ensure proper tension and alignment of the new belt.

4. Brake Inspection

Remove the wheel to access the brake assembly.
Check brake pads for excessive wear and the rotor for overheating.
If necessary, replace worn brake components and ensure calipers are functioning properly.

5. Test Drive

After completing the inspection and repairs, take the vehicle for a test drive.
Monitor for any residual smells or abnormal sounds.
