Valve is on the input side.  As to which of the two hoses is which, the
input to the heater should come off the cylinder head (source of hottest
water). I know nothing about the Tiico, but the way to be sure is to crank
it over with the spark disabled and see which hose coolant comes out of.

Subject: Heater Hose routing

Last summer a mechanic by-passed my front Heater Core due to a small leak. I
have installed a new heater core and fan motor+ wiper motor Just to be
proactive. My question is which heater hose is the feed hose and which is
the return hose?  While laying down with the radiator fan above me I see two
hoses along the frame rail and a open hose from the new Heater Core with the
valve beside it open as well. So which Hose along the frame rail is the feed
hose, the outside Hose or the inside Hose? Which Hose goes to the Heater
Valve?
  Thanks, Bill Witz  84 Tiico   Doing my part to keep this Westy on the
road.
