Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, screwdriver set, fluid dipsticks, safety glasses.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect Engine and Transmission Fluid

Engine Oil Check:
1. Remove the engine oil dipstick and wipe it clean.
2. Reinsert the dipstick and remove it again to check the oil level.
3. If the oil is low, top it off with the manufacturer-recommended oil.
Transmission Fluid Check:
1. Locate the transmission dipstick (if applicable).
2. Remove the dipstick, wipe it clean, and reinsert it.
3. Check the fluid level and condition. If it is low or burnt, replace the fluid.

3. Inspect Serpentine Belt and Pulleys

Visually inspect the serpentine belt for cracks, fraying, or wear.
Check the condition of the pulleys by spinning them by hand and listening for noise.
If any components are damaged, replace the serpentine belt and/or pulleys.

4. Examine Differential Fluid

Locate the differential fluid fill plug.
Remove the fill plug and check the fluid level; it should be just below the fill hole.
If the fluid is low or dirty, drain it and refill with the manufacturer-recommended differential fluid.

5. Reconnect Battery and Test Drive

Reconnect the battery and start the vehicle.
Test drive the vehicle to verify that the whining noise has been resolved.
