instead of using the drain plug I used the large lower court hose to drain the fluid. I assumed that this would be a low enough of a point on the engine that it would fully drain but when I remove a freeze plug it was full well above the freeze plugs in Augusta all over the place. it looks like a previous mechanic slam some group in the dream and I'm afraid to remove it for fear that it was actually break. is there another location where I can drain it from on a hose rather than from the radiator . is it possible something's blocking the flow ?
