Solution

1. Preparation

Gather tools: OBD-II scanner, fluid pump, wrench set, clean rags, power steering fluid.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety during repairs.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir, typically near the engine compartment.
Remove the cap and check the fluid level against the markings.
If low, add the recommended type of power steering fluid as per the owner’s manual.
Replace the cap securely.

3. Inspect and Repair Leaks

Examine all power steering hoses and connections for signs of leaks.
If leaks are found, tighten loose connections or replace damaged hoses.
If the power steering pump is leaking, remove it using the following sub-steps:
- a. Disconnect the power steering pump belt using a wrench.
- b. Remove the mounting bolts and carefully extract the pump.
- c. Install the new pump by reversing the removal steps, ensuring all bolts are torqued to specifications (usually around 15-20 ft-lbs).

4. Test Power Steering System

Reconnect the battery.
Start the engine and turn the steering wheel from lock to lock to bleed air from the system.
Check for any abnormal noises and ensure the steering responds normally.

5. Recheck Fluid Levels

After testing, recheck the power steering fluid level.
Add fluid if necessary and monitor for leaks.
