Try disconnecting the cable from the valve on the thermostat housing and see if you can close it further and shut off the flow. It might just be clamped at the wrong place on the cable. You'll also be able to check the cable inner runs smoothly in the outer. I think they are supposed to lock at the cabin end when you twist them a bit too, like the choke.

The TC heater valve is famous for needing "help" to close fully.  The S1/2 heater valve is famous for not closing fully no matter what you do.

I know this is resurrecting an old thread...but...if you switch the hose positions on the valve..it usually works better, since it's just a flat piece of metal that covers the inlet hole, but the pressure of the water flow cracks it open a tad.  If you reverse the hose positions (may take some fiddling...), the pressure will be against the back of the valve flap instead of the side facing the hose connection, so it will keep it closed.
