Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, socket set, screwdriver set, stethoscope (optional).
Ensure the vehicle is parked on a level surface and the engine is off. Engage the parking brake.

2. Serpentine Belt Inspection and Replacement

Locate the Belt: Open the hood and locate the serpentine belt.
Check for Damage: Inspect the belt for cracks, fraying, or excessive wear.
Remove the Belt: Use a socket wrench to relieve tension on the belt tensioner and remove the belt.
Replace with New Belt: Install a new serpentine belt according to the manufacturer’s routing diagram.

3. Transmission Fluid Check and Change

Locate the Transmission Dipstick: Pull the dipstick to check fluid level; add fluid if low.
Inspect Fluid Condition: Check for a burnt smell or dark color, indicating a need for change.
Drain Transmission Fluid: If a change is needed, remove the drain plug and let the fluid drain completely.
Replace Filter: If applicable, replace the transmission filter following manufacturer guidelines.
Refill Transmission: Use the appropriate type of transmission fluid and refill to the proper level.

4. Differential Inspection and Fluid Change (if applicable)

Check Differential Fluid Level: Locate the differential fill plug and remove it to check fluid level.
Drain Old Fluid: Remove the drain plug and allow fluid to drain completely.
Replace Differential Fluid: Refill with the correct type of differential fluid until it reaches the fill level.
