ICBW is shorthand for I Could Be Wrong!
Some of what Steve is saying makes me question my understanding of how the dash heater works. When Steve indicates it seems to leak depending upon usage, that almost implies that usage controls the water through the core.
I had always thought that water flows through the core all the time ( the enigne is running ) regardless of any setting of the heater controls. I thought the controls moved air flaps that when heat was requested, routed air through the core. Does anyone know for sure if the heater control moves flaps as I speculate, or actually operates a water valve and throttles coolant through the core?
I have attached a picture of the valves ( under the hose, sorry about that ) in the engine compartment that would allow one to valve off the heater core should that ever be necessary. Russ
