Got the 39 radiator back today, need a new drain valve for radiator, leaks and has very little resistance, I was always afraid it might vibrate open. Next thing I need to do is push car outside and flush the block out while I have the water pumps removed, would like to have ideas on what process you have used to clean/flush out. I was thinking of making a adapter for the head water outlet and connect water hose. Then blank of the water pump opening and fill up, do a quick release of water with water turned on? Might see if I can make a water wand out of small copper tube (1/4") and flush out area in water pump opening.
