4-5hours, I don't remember it taking that long. The write up is pretty much like mine though. I used a long bar extension on my breaker bar to release the tensioner, it takes quite a bit of torque, but I was able to inset a drill bit into the holding hole to keep the tensioner out of the way. There are a couple of plastic points on your fan cover, these will tear up your arms when working there. I cut them off and sanded them smooth before starting. I also used an inspection mirror to see it the belt was installed around all the pulleys properly. It is a pain in the behind to replace, but not the worst job on the Jeep. The hardest thing for me was connecting the turbo connection to the outlet of the turbo resonator (the black kidney shaped thing), the first time it was not set properly and blew off down the road. You can limp back to your shop slowly though.
