1. Locate the power steering reservoir and remove the cap.
2. Check fluid level; if low, top up with manufacturer-recommended fluid.
3. If fluid is dark or contaminated, drain the old fluid using a fluid pump.
4. Refill with fresh power steering fluid and replace the cap securely.

3. Check and Replace Serpentine Belt

Sub-steps:
1. Loosen the tensioner pulley using a socket wrench.
2. Remove the old serpentine belt from the pulleys.
3. Inspect the tensioner and pulleys for wear.
4. Install the new serpentine belt following the routing diagram.
5. Tighten the tensioner back to specification.

4. Inspect Differential and Transmission Fluid

Sub-steps:
