took me about 2 hours first time and about an 1 1/2 hours the second time.
Also I took a few pics for those that want to tackle this and don't have a vice.
I didn't have a vice so I used a socket (forgot the size but whatever fit through the hole in the pulley) and the 19mm wrench to get the pulley off.
Instead of using a swivel socket or uv joint I just pulled off a few of the connectors adjacent to the bolt and used a 3/8" wrench to get at the hard to reach bolt.
Hope this helps anyone that will be tackling this. FYI, buy the OEM pump, screw all the crap from autozone, oreily, etc. The OEM actually came with the pulley, O-rings and pressure switch connector.
