Thanks for all the input. A follow up question for 4onthefloor, I will look when I get down to my shop this weekend but how could that lower opening on the water outlet be plugged when the thermostat opens? its a ways below the thermostat housing. I can understand the upper outlet doesn't move any coolant until the thermostat opens because it appears to be above the base of the thermostat. Am I misunderstanding what you wrote? Darn I have being thickheaded.
