- If leaks are found at the pump or gear, inspect and replace any worn seals or O-rings.

3. Fill Power Steering Fluid

Refill:
- Using a funnel, refill the power steering reservoir with the appropriate type of power steering fluid as specified in the owner’s manual.

4. Test the System

Start the vehicle and turn the steering wheel from lock to lock to help purge air from the system.
Check for any signs of leaks while the system is under pressure.
