I'm thinking now you are probably right......I didn't bleed for that long out
there....getting rained on.  I bet when I go back out there tomorrow when
she's cool, it'll be bone dry in the tank.  I took for granted the coolant
necessary for these things the first time I did it back last year too!!  I've
read it in archives here and there too and still, when I do that coolant
change, I end up like, are you serious, you want more coolant?  :-)   As it
drinks I think... the thing must be leaking underneath somewhere!...and I
look, and no, it's not....these things just take a hec of alot of liquid.
