Neil,
  I would try pressurizing the cooling systm to at least 15 psi while you
check for leaks.  My setup uses an old coolant cap with the valves taken
out, pressure gauge, hoses, clamps, and a valve stem.
   I have found that screw clamps need to be retightened from time to time
after being installed on new hoses.

  What fun.
