Inspect the inside of the reservoir for any debris or contamination.

3. Examine Hoses and Connections

Trace the power steering hoses from the reservoir to the steering rack and pump.
Look for any signs of wear, cracks, or leaks in the hoses.
Tighten any loose clamps or connections if necessary.

4. Check Steering Rack and Pump Area

Clean any visible fluid with a cloth to better identify new leaks later.

5. Pressure Test (if needed)

Connect a pressure gauge to the power steering system.
Start the engine and turn the steering wheel full lock in both directions to check for pressure drops.
Note any significant drops which may indicate internal leaks.
