Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, OBD-II scanner, socket set, and torque wrench.
Ensure the vehicle is parked on a flat surface and the engine is off before beginning work.

2. Fluid Inspection

Sub-steps:
1. Open the hood and check the engine oil level using the dipstick.
2. Inspect the transmission fluid level through the dipstick tube, ensuring the vehicle is at the correct operating temperature.
3. Inspect the power steering fluid reservoir for proper levels.

3. Component Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Check the condition of the drive belts for cracks or fraying.
3. Inspect pulleys for wear or misalignment.
4. Examine the differential and transmission for signs of leaks or damage.

4. Addressing Power Steering

Sub-steps:
1. If the power steering fluid is low, refill it with the manufacturer-recommended fluid.
2. If there are signs of a leak, replace the power steering pump or hoses as necessary.

5. Drive Belt Replacement (if needed)

Sub-steps:
1. Loosen the tensioner pulley using a socket wrench and remove the old drive belt.
2. Install the new belt, following the correct routing diagram.
3. Reapply tension to the belt and ensure it is properly aligned.
