Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure the engine is off.
Disconnect the battery to prevent electrical short circuits.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add the recommended fluid type if low.
Inspect the fluid for contaminants or discoloration; if dirty, proceed to replace it.

3. Inspect and Repair Leaks

Visually inspect hoses and connections for leaks.
If leaks are found, replace the damaged hoses or seals.
Use a clean cloth to wipe any spills and ensure the area is dry.

4. Replace Power Steering Pump (if necessary)

Remove the serpentine belt using a tensioner tool.
Disconnect the power steering pump from its mounting bracket.
Detach the fluid lines from the pump and remove the pump.
Install the new pump by reversing the removal steps. Torque the mounting bolts to manufacturer specifications.

5. Bleed the Power Steering System

Refill the power steering fluid reservoir.
Start the engine and turn the steering wheel from lock to lock to expel air from the system.
Check the fluid level again and add more if necessary.
