Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal to prevent electrical shocks.
Gather necessary tools: socket set, torque wrench, and OBD-II scanner.

2. Inspect and Replace Engine Belts

Sub-steps:
1. Remove any engine covers as necessary to access the serpentine belt.
2. Inspect the belt for cracks or fraying; replace if damaged.
3. Use a wrench to relieve tension from the tensioner pulley and remove the belt.
4. Install the new belt, ensuring it is routed properly according to the belt diagram.
5. Reattach any covers and reconnect the battery terminal.
Tools Required: Socket set, belt tensioner tool (if needed).

3. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission fluid dipstick or fill plug.
2. Remove the dipstick and check the fluid level; add fluid if low.
3. If the fluid is dark or burnt, consider a fluid change:
  - Drain the old fluid using a drain pan.
  - Replace the transmission filter (if applicable).
  - Refill with recommended transmission fluid type as specified in the owner's manual.
Tools Required: Socket set, drain pan, funnel.

4. Differential Fluid Inspection (if applicable)

Sub-steps:
1. Locate the differential fill plug on the rear axle.
2. Remove the fill plug and check the fluid level; add fluid if low.
3. If the fluid appears dirty or has a burnt smell, drain and replace it:
  - Remove the drain plug, allow fluid to drain completely.
  - Reinstall the drain plug and refill with new differential fluid.
Tools Required: Socket set, drain pan, funnel.
