Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Serpentine Belt

Tools Required: Socket set, belt tensioner tool.
Steps:
1. Locate the serpentine belt routing diagram (usually found on a sticker in the engine bay).
2. Use the belt tensioner tool to relieve tension on the serpentine belt.
3. Remove the old belt from the pulleys.
4. Inspect the pulleys for wear or damage.
5. Install the new serpentine belt according to the routing diagram.
6. Reapply tension using the tensioner tool and ensure the belt is seated properly.

3. Check and Replenish Power Steering Fluid

Tools Required: Funnel, clean rag.
Steps:
1. Locate the power steering fluid reservoir.
2. Check the fluid level against the minimum and maximum marks.
3. If low, clean the area around the reservoir cap, remove it, and use a funnel to add the recommended power steering fluid.
4. Replace the cap securely.

4. Transmission Fluid Inspection and Replacement

Tools Required: Transmission fluid pump, socket set, drain pan.
Steps:
1. Warm up the engine to operating temperature and park on a level surface.
2. Locate the transmission dipstick (if applicable) or drain plug.
3. If using a dipstick, remove it and check fluid level and condition (should be pink/red and not burnt).
4. If fluid is low or dirty, drain the old transmission fluid into a pan and replace with new fluid using a fluid pump.
5. Replace the drain plug and torque to the manufacturer's specifications.

5. Reassemble and Test

Reconnect the battery.
Start the engine and allow it to idle for a few minutes.
Test drive the vehicle to verify that the whining noise has been resolved.
