If you clamp the hoses and leave them attached to the cooler, there isn't
enough play in the hoses to get the cooler over the threaded pipe and free
the o-ring. You have to remove the hoses or back the threaded pipe out of the
engine block. Trust me, I tried to just clamp the hose and there was no way
to get the cooler off the pipe that way. I did the "remove the hoses" thing
as I didn't have a big nut for the threaded pipe, and it's a difficult job
that way. There is very little room, it's hard to get the hoses back on and
mine developed coolant leaks a couple of times and became another job to deal
with. Backing the threaded pipe out seems like a much easier way (although I
didn't actually try it that way myself).
