Locate the power steering pump, usually at the front of the engine.
Remove the drive belt by loosening the tensioner pulley.
Disconnect the power steering lines from the pump using a wrench.
Remove the mounting bolts securing the pump and take out the pump.
Install the new pump and reconnect the power steering lines securely.
Reinstall the drive belt and ensure proper tension.
