Hi,
Ditto, we had leakeage for years with the worm drive clamps. As the
inner metal fitting heats first (and expands) it crushes the hose
against the clamp, which does not heat as quickly. As it cools, the
crushed hose now has space for coolant to leak from. Later on, you
notice the loose clamp and tighten it a little. The next time you run
the engine, the process repeats itself. We finally switched to spring
clamps and have not had the problem since.

Hi Richard,
It has been my experience that worm drive clips will ultimately leak due
to
the thermal expansion & contraction from summer to winter. I ended up
using
the spring clips similar to what Rotax use for the coolant hoses on the
top
of the engine.
Cheers, Paul
