Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and turn off the ignition.
Disconnect the battery to ensure safety while working on the electrical components.

2. Inspect and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if low, add the recommended fluid (usually ATF or specific power steering fluid).
If the fluid is dark or contaminated, proceed to flush the system.

3. Check for Leaks

Visually inspect all power steering hoses, fittings, and the pump for signs of leaks.
If leaks are found, replace the damaged hose or fitting using a socket set to remove and install new components.

4. Replace Power Steering Pump (if faulty)

Remove the serpentine belt from the power steering pump.
Disconnect the power steering lines from the pump, using a wrench to avoid damage.
Remove the bolts securing the pump to the bracket and take out the pump.
Install the new pump by reversing the removal steps, ensuring all connections are tight and no leaks are present.

5. Final Assembly

Reinstall the serpentine belt according to the routing diagram usually found on the engine bay.
Reconnect the battery.
Start the engine and turn the steering wheel from lock to lock to bleed any air from the system.
