Trying to flush my radiator and I ran into a bit of a problem - the stupid valve on the radiator when opened, didn't result in even as much as a drop.* Based on some google recommendations, I tried shoving a narrow zip tie into the valve to dislodge if need be... nothing... tried blowing compressed air into it... still nothing.....
So for now I just popped the lower hose and swapped as much coolant as I could that way.... pulled someplace between 6 and 7 quarts... which means that there is still plenty left.* I wanted to do the add distlled water, drain repeat to get as good of a flush as possible but I ended up doing just a partial drain and refill.
Anyways, what's up with the stupid valve???* Any ideas as to the best flush possible?
Anyway you can remove the whole petcock assembly and then push into it with zip tie in? I know some have the bung welded in place.
