Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety: Wear gloves and safety goggles.

2. Check Fluid Level

Open the hood and locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the markings.
If low, proceed to the next step; if adequate, investigate further.

3. Refill Power Steering Fluid

Use the manufacturer-recommended power steering fluid.
With a funnel, carefully add fluid to the reservoir until it reaches the appropriate level.
Replace the cap securely.

4. Inspect for Leaks

Visually inspect hoses, connections, and the pump for any signs of fluid leaks.
If leaks are found, identify the source and proceed to replace the faulty hoses or pump.

5. Replace Power Steering Pump (if necessary)

Disconnect the negative battery terminal.
Remove the serpentine belt by loosening the tensioner.
Unscrew the power steering pump from its mounting bracket.
Disconnect the fluid lines and remove the pump.
Install the new pump by reversing the removal steps, ensuring all connections are tight.
Refill the power steering fluid and bleed the system by turning the steering wheel from lock to lock several times.
