Edit: the GOOD news is that you can replace it in less than 10-15 minutes. hand-strength belt tensioner.. 8 bolts (IIRC) on the housing and off it comes.. tada.
Maybe you can do it in that time but I think it takes longer than that. Maybe if you don't care about the coolant spilling all over by not opening the radiator drain that time is possible. Plus the hoses with the factory clamps? 15 minutes is fast.
there are no hoses to remove unless you are repalcing the housing,...
