It all started two weeks ago when I was leaving Athen's Ga for the three
hour ride home. I had been driving in town for a while when I stopped for
gas.When I opened the door to get out I hear a hissing and look on the ground to see
approx. 3 gal of anti freeze heading down the parking lot. I look under to
find a large hose completely off. After looking around some more I see also the
cap says for flushing also blown off. I replaced all the hoses and drove home
with no problems wondering what would cause pressures to blow them off.  Made
it home and have been driving the van for a couple of weeks when another hose
started to forcefuly leak out coolant and I could see it was under great
pressure.
 What could be causing this? Is it the cap not releasing pressure?I thought I
had bled it well but could air in the lines cause this? I don't smell any
exhaust fumes. Van seems to run well. Heat works. Does not over heat.Did great
for probably 400 miles. Anyone have any ideas?       Merv
