Re: 52 v8 flathead heater
Thank you Merc Cruzer. I took the valve out. Cleaned it. Ran water thru it and it flows without obstruction. If I blow thru a tube it wont release air. If I apply vac to it, the inner diaphragm moves a tiny bit. I dont think it is any good. I still feel the core is plugged. I will move the valve to the head and remove the lower tube to check for water. Weather is against me right now. Wishing for a garage this Xmas?
