I had the radiator of my 1969 MM 670 Super Gas refurbished a couple years ago because it had a leak. Since then, it has been fine. However, when I was checking the fluids the other day in preparation for running it for the first time this season, I was very surprised to see that the top tank of the radiator had NO coolant in it. It was fine last fall when I put it in the barn for the Upper Midwest Winter, then pretty much dry now. As far as I know, it does NOT have a leak and there is no sign of leaking, like stains on the floor, stains or liquid gathered somewhere where one would expect to see it if it had been leaking. I have been around tractors all my life and never recall coolant disappearing out of the top tank during the winter months. Here is my somewhat stupid questions: Any ideas why?
