Usually taking the intake tube, air filter box, battery, and the hose off of the radiator will give plenty of room (fold it back).
To get a hose off of an aluminum nipple, pull at one spot and mabe slide something dull under the hose end. Not a screwdriver or a knife, more like a letter opener.
Use scotch-brite to get the corrosion off of the nipple and make sure the hose is not dammaged or you will drown your engine when you start it and that sux.
