Solution

1. Preparation

Gather the necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical shorts.

2. Check and Refill Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; if low, add the appropriate power steering fluid as specified in the owner’s manual.
Inspect for any signs of contamination in the fluid. If contaminated, flush the system.

3. Repair or Replace Leaking Hoses

Identify any leaking hoses by visually inspecting all power steering hoses.
If a hose is damaged, use a wrench to disconnect the hose from the reservoir and steering rack.
Replace the damaged hose with a new one, ensuring all connections are tight and secure.

4. Inspect and Replace the Serpentine Belt

Locate the serpentine belt and inspect for cracks or wear.
Use a wrench to relieve tension on the belt tensioner and remove the old belt.
Install a new serpentine belt according to the routing diagram located on the engine bay.

5. Reassemble and Test

Reconnect any components that were removed.
Refill the power steering fluid to the proper level.
Reconnect the battery and start the vehicle.
Test the steering to ensure that the hissing noise is eliminated.
