I am replacing the heater control valve on my 85 Vanogon.  I spent one hour last
night trying to get the upper spring hose clamp off and was not successful.  Any
tips or tricks on how to make this job go easier would be appreciated.  I
searched the archives and just found more tales of whoa and no good advice on
how to do this replacement.

TIA,

Vince.
