If you already have 1 sitting there it shouldn't be too hard at all. You may have to swap the pulley over tho' in which case you might need a puller for that. Other than the pulley there are just a couple bolts and 2 hoses to undo. Take like a turkey baster or something similar and try to suck as much fluid out as possible because the hoses are on the bottom. The bolts are accesible from holes made into the pulley. Just rotate the pulley til the hole lines up with a bolt and undo them. The pulley is a press fit so if the new (or old) pulley wont go on, get a longer bolt and slide the bolt through a socket and tighten the bolt down on the socket and it will in essence "press" the pulley on to the new pump. Not sure if the hoses are flare fittings or not. If they are you don't even need to seal the threads, the flare should seal the fitting.
