I am moving on this pretty quick, I couldn't stand letting it sit overnight,
so I went outside and removed the main (expansion) tank, I lost what I
presume to be the lions share of the coolant when removing the hoses. I took
the tank into the house, plugged up the openings with my finger and blew
into it (with the cap on), I can't get any air to come out, but I do see
some spider web type of cracks at the base of the filler neck. But like I
said it holds as much pressure as my mouth can put into it. Maybe tomorrow I
will look at the hoses.
