That's the one Dave... It always flows coolant and is not affected by the Tstat. And as to the earlier question... if the system is desgned right, the stat should open and stay at least partially open to maintain the temp. If it was overengineered it might close but you'd have to be runnign water less than you Tstat temp rating under it... so i dont thin that would happen.

LAR, the bypass blocked? Really? Never heard of that before. Heater lines sure, not the bypass.


Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
