Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, fluid containers for oil and transmission fluid.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery if working on electrical components.

2. Inspect Serpentine Belt

Tools Required: Socket set, flashlight.
Remove the engine cover if necessary.
Visually inspect the serpentine belt for cracks, fraying, or signs of wear.
If damaged, replace it with a new belt. Torque the belt tensioner as per manufacturer specifications.

3. Check Engine Oil

Tools Required: Oil filter wrench, oil catch pan.
Remove the oil dipstick and check for oil level and condition (milky or burnt).
If low or dirty, drain old oil, replace with new oil of appropriate grade, and replace the oil filter.

4. Inspect Transmission Fluid

Tools Required: Transmission fluid dipstick, funnel.
Check the transmission fluid level and condition using the dipstick.
If low or contaminated, drain the fluid and refill with the manufacturer-recommended transmission fluid.

5. Inspect Wheel Bearings and CV Joints

Tools Required: Jack and jack stands, socket set.
Lift the vehicle and remove the front wheels.
Inspect the wheel bearings for play and noise by spinning the hub.
Inspect CV joints for cracks or grease leakage. Replace if necessary.
