Gawd I gotta stop talking to myself :)
I friend mentioned he heard some shop  talk that you should really use
spring clamp on silicone because it has more of a tendency to expand/contact
more so than rubber coolant hose & using the smooth faced gear clamps it has
more a tendency
to weep at the joins ???
any experience here / first hand knowledge ??
