Poodles- Go with the 2 piece if it puts your mind at ease. But the one piece has thus far proven to be reliable.
I give an utmost amount of credit to Shaftmasters for creating a 2 piece for the Supra.
These guys are a pleasure to work with.
Like jdub said, our 1 piece ds are excellent, 11.5lbs...
Are you getting vacuum to the diaphragm?
The valve is difficult to open by hand, vacuum easily pulls it open.
Do you have a hand vacuum pump to test it just to make sure?
I have bypassed it before while waiting for the replacement valve.
It just constanty flows hot coolant into the heater core, tolerable in the winter.
But it could get quite hot in the cab in warmer climates.
Confirm your heater valve is actuating.
The lines can be hot (heat soak from the engine) but still have no flow.
If the valve is opening, your core could be plugged or you have another part in the system that is bad.
