Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Serpentine Belt

Inspect the serpentine belt for damage:
- Check for cracks, fraying, or wear.
If damaged, replace the serpentine belt:
- Use a socket set to loosen the tensioner and remove the old belt.
- Install the new belt following the routing diagram located in the engine bay.
- Ensure the belt is properly seated on all pulleys.

3. Check and Refill Power Steering Fluid

Locate the power steering reservoir:
- Check the fluid level against the markings on the reservoir.
If low, refill with manufacturer-recommended power steering fluid:
- Use a funnel to prevent spills.
- After refilling, turn the steering wheel from lock to lock to bleed any air out of the system.

4. Inspect and Replace Transmission Fluid

Check the transmission fluid:
- Remove the dipstick and check fluid level and condition.
If fluid is low or burnt:
- Drain the old fluid using a transmission fluid pump.
- Replace with the manufacturer-recommended transmission fluid.
- Reinsert the dipstick and ensure it is seated properly.
