the PS steering pump is held on by 2 12mm bolts(if memory serves me correctly). you have to go through the PS pulley with a socket in order to get to them.
12. put everything else back on(including PS cap)....start vehicle...turn wheel left and right 5 more times, turn off vehicle. recheck fluid level. recheck PS lines for leaks. if no leaks are found, great job, now put the old pump back in the box, and return it for a core charge. and grab a bear and sit down. like to add, if you have small hands....this job should not be a problem...
