Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather necessary tools and parts for the repair.
Safety warning: Disconnect the battery before working on electrical components.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and wipe the dipstick clean.
Check the fluid level against the markings on the reservoir and add the appropriate power steering fluid if low.
Replace the cap securely after checking.

3. Inspect and Replace Power Steering Pump (if necessary)

Remove the serpentine belt from the power steering pump using a socket set.
Disconnect the power steering lines from the pump with a wrench, capturing any leaking fluid in a container.
Unbolt the power steering pump from its mounting bracket and remove it from the vehicle.
Install the new power steering pump by reversing the removal steps. Ensure all bolts are tightened to manufacturer specifications.
Reconnect the power steering lines and replace the serpentine belt.

4. Check for Leaks

Start the vehicle and allow it to idle.
Turn the steering wheel from lock to lock while observing for any leaks around the pump and hoses.
If leaks are present, tighten fittings or replace damaged components as needed.
