Would it be wise to install a three way valve that returns the water back into the system through the heater return hose? I may be completely off key here but I thought I'd ask!

Can you add to that Tim?

Mando,
Here is my understanding per the ERA manual …
- Install the water shut-off valve in the water outlet of the intake manifold … connect to the lower tube on the heater (inlet) ...
- Connect the upper heater tube (outlet) to the fitting on the water pump ...
- (also) If you are using a heater … drill a small bypass hole in the thermostat next to the bulb so that a small amount of water bypasses constantly …
So in my setup, the water source is from the brass 'T' on top of the intake manifold. Had there been more room under the distributor, I would have mounted the water temperature sending unit there, and used just a 1/2" npt to 5/8" hose fitting, connected to the heater inlet valve.
The water then exits out the 'upper' heater core hose, to the water pump (to the plastic 'T' in my case) that also joins in with the expansion tank. This setup should work, I'll let you know how it goes.
As far as 'dead' or non circulating water is concerned, the valve is only on one side, so there may be some water mixing but probably not a whole lot. One could crack open the valve just a bit to get some recirculation from time to time. Be sure to leave the valve open with bleeding air out of the system.
Hope this helps … anyone else have any input for Mando?
