If a leak is found, replace the damaged hose or fitting with a new one.
Tighten any loose clamps or fittings.

4. Replace Power Steering Pump (if necessary)

Loosen the power steering belt tensioner and remove the belt.
Disconnect the power steering pump from the lines and wiring harness.
Remove mounting bolts securing the pump and take out the old pump.
Install the new power steering pump and reattach all connections.
Reinstall the belt and adjust tension as per manufacturer specifications.
