Thanks Mister Towed,

My description was incorrect. The top radiator hose does go to the thermostat housing. Bottom radiator hose feeds from the water pump.

On Pistonheads the suggestion is that I need to change:
a) Expansion tank should feed into bottom radiator hose.
b) Add connection from radiator filler drain (always open on Honda radiator I think?) to the expansion tank top (but not vent).

Does this make sense?
