Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a flat surface and secure with wheel chocks.

2. Inspect and Top Off Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add the recommended power steering fluid if low.
Check the condition of the fluid; if it appears dark or contaminated, proceed to replace it.

3. Check for Power Steering Leaks

Visually inspect hoses and connections for signs of fluid leaks.
If leaks are found, replace the damaged hoses or seals as necessary.
Clean any spilled fluid before rechecking the level.

4. Replace Serpentine Belt (if applicable)

Loosen the tensioner pulley using a socket wrench.
Remove the old serpentine belt from the pulleys.
Install the new serpentine belt according to the routing diagram usually found on a label under the hood.
Tighten the tensioner back into place.

5. Replace Power Steering Pump (if necessary)

Remove the power steering pump by disconnecting the inlet and outlet hoses, and unbolting it from the mounting bracket.
Install the new power steering pump and reattach all hoses securely.
Refill the power steering fluid reservoir and bleed the system by turning the steering wheel from lock to lock.
