Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, fluid catch pan, power steering fluid, and cleaning cloths.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and inspect the fluid level; it should be between the “MIN” and “MAX” marks.
If low, add the recommended power steering fluid type (check the owner’s manual).

3. Inspect and Repair Leaks

Clean the area around the power steering pump and steering gear.
Look for any visible leaks in hoses or connections.
If leaks are found, replace the damaged hoses or seals as needed.
Refill the power steering fluid after any repairs.

4. Replace Power Steering Pump (if necessary)

Disconnect the battery to ensure safety.
Remove the serpentine belt from the power steering pump.
Unbolt the power steering pump from its mounting bracket.
Disconnect the fluid lines carefully, allowing any residual fluid to drain into the catch pan.
Install the new pump by reversing the removal steps, ensuring all connections are tight.
Reattach the serpentine belt and reconnect the battery.
