Examine power steering hoses and connections for any signs of leaks.
If leaks are found, replace damaged hoses or fittings.
Use a power steering hose clamp tool and appropriate size replacement hoses.

4. Replace Power Steering Pump (if necessary)

Remove the serpentine belt from the power steering pump by using a wrench to relieve tension.
Disconnect the power steering lines from the pump using appropriate line wrenches.
Remove the mounting bolts securing the pump to the engine.
Install the new power steering pump by reversing the removal steps, ensuring all connections are tight.
