Jeff,
This probably goes without saying, but I have to ask anyway. = ; I'm assuming you put beads on all of the radiator connections?&= nbsp;Commercial radiators normally come with beaded fittings.  I'm mor= e curious about the sweep L's and other pieces of tubing in your syste= m. I am aware of at least one rotary a/c that made an emergency landing aft= er having a hose blow off in flight.  If not, Earl's Supply = sells beading tools that do a pretty fair job for the price.
