Can't find the drain or I am missing something. If you need the serial # of the Behr is 1R759 67129
Spoon Sports 4/10/2011Probably the drain plug hole is plugged with rust. Because that is the drain hole, anyway what i would do at this point is remove the radiator hang it upside down to drain the water.
Never use tap water, use distilled water (Dont want to explain it since its a long read for you)
