Trying to flush coolant system in my 1988 62. I drained all of the coolant from the bottom of the radiator out of the petcock. However, when I went to fill the radiator, it only except in a few tablespoons through the top and really never did go down. I could not get any more coolant into the radiator. The neck on the radiator where the cap goes on seems to be angled downward a bit from the top of the radiator, but I don’t see that as being the ultimate problem, because the radiator was filled to the top before I drained it. Also, before anyone asks, yes the radiator completely emptied when I opened the petcock. What completely simple and stupid thing am I overlooking? Thanks in advance,
Grant
