Solution

1. Preparation

Gather all tools and parts needed before starting.
Ensure the vehicle is parked on a level surface with the engine off and cool.

2. Inspect and Replace Drive Belts

Sub-steps:
1. Open the hood and visually inspect the serpentine belt for cracks or fraying.
2. If damaged, use a socket set to loosen the tensioner and remove the old belt.
3. Install a new belt, ensuring it follows the correct routing path.
4. Tighten the tensioner to the manufacturer's specifications (typically around 30-50 Nm).

3. Check and Refill Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir and remove the cap.
2. Check the fluid level against the markings on the reservoir.
3. If low, add the recommended power steering fluid (check owner's manual for specifications).
4. Replace the cap securely.

4. Inspect and Replace Transmission Fluid (if needed)

Sub-steps:
1. Ensure the engine is warm and the vehicle is on level ground.
2. Remove the transmission dipstick and check fluid level and condition.
3. If fluid is low or contaminated, drain and replace it using the appropriate transmission fluid (as per the owner's manual).
4. Reinsert the dipstick and ensure a proper seal.
