Please forgive me as I truly own a Chevy Venture (but have a GTO in the garage). I was about to attempt to replace the WP on the wifes van this weekend and backed off in a moment of intimidation. It appears as easy as removing the belt guard, the belt and then the pully and finally the pump.

If anyone knows this to be more complex for someone without air tools or a desire to remove the passenger tire and splash guards I would greatly appreciate it.
