If the pump is noisy or damaged, remove the serpentine belt from the power steering pump.
Disconnect the pump from the mounting bracket and remove the inlet and outlet lines.
Install the new power steering pump, reconnect the lines, and secure it with the mounting hardware.
Reinstall the serpentine belt, ensuring proper tension.

5. Test the Steering System

Reconnect the battery and start the engine.
Turn the steering wheel from lock to lock to circulate the new fluid and check for leaks.
Monitor for any noises or issues during operation.
