Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal for safety.

2. Check and Refill Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; add power steering fluid if low.
Inspect the fluid for contamination; if it's dark or has debris, it may indicate a problem.

3. Inspect and Repair Leaks

Visually inspect power steering hoses and connections for any signs of leaks.
If a leak is found, replace the affected hose or fitting as necessary.
Clean the area around the leak to monitor for new fluid seepage after repairs.

4. Replace Power Steering Pump (if necessary)

Remove the serpentine belt by loosening the tensioner with a wrench.
Disconnect the power steering pump from the reservoir and unbolt it from the engine.
Install the new power steering pump, ensuring all connections are secure.
Reconnect the serpentine belt, ensuring proper alignment.

5. Bleed the Power Steering System

Fill the power steering reservoir with the recommended fluid.
Start the engine and turn the steering wheel from lock to lock several times to purge air from the system.
Check the fluid level and add more if necessary.
