If you have room, think about studs for the pump flange. It was always easier for me to hang a fan on the studs than try to hold it, spin it to try and find the holes and get bolts in. Some fans have slotted holes that make it easier but....
Usually you can leave the shroud loose and shoved back toward the engine, slide the radiator down in and mount it, then bring the shroud back up to the radiator and mount it. Putting a fan on with the shroud in place is pretty tough. It can be done but be prepared with extra bolts, washers etc so when you drop them into the black hole you will have more. Also, keep the kids away so they won't hear the cussing.
