I've used it for emergencies --- I was 3 hours into a 6 hour trip; stopped
for coffee and came out to a pool of coolant on the ground. I could see the
leak in the rad :-(   Put in some Barr's --- it got me to my destination
(BusFusion) and back again. Didn't leak a drop. Going against a lifetime of
"if it ain't broke, don't fix it" I wimped out and changed the rad. Must be
getting old.

Cheers,
Doug
