Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, pressure gauge, fluid catch pan, funnel.
Disconnect the negative battery terminal to avoid electrical issues during repairs.

2. Check Power Steering Fluid

Remove the power steering fluid reservoir cap.
Inspect fluid color and level; if low, top off with the manufacturer-recommended fluid.
If fluid is dark or contaminated, proceed to flush the system.

3. Inspect and Repair Leaks

If leaks are found, replace any damaged hoses or seals.
- Sub-steps:
  - Remove clamps and disconnect the affected hoses.
  - Install new hoses, ensuring secure connections and replace any O-rings or seals as needed.
Clean the area around the leak to monitor for new leaks after repairs.

4. Replace Power Steering Pump (if necessary)

If the pump is faulty, remove it:
- Disconnect the fluid lines using a wrench.
- Remove the mounting bolts and lift out the pump.
Install the new pump:
- Position the new pump and tighten mounting bolts to manufacturer specifications (typically 15-25 ft-lbs).
- Reconnect the fluid lines and ensure there are no leaks.

5. Bleed the Power Steering System

Fill the reservoir with power steering fluid.
Turn the steering wheel from lock to lock several times to purge air from the system.
Check fluid level and top off as necessary.
