Draining coolant
W211 E63
I've searched the forum to no avail.
I replaced my Radiator and drained all I could. Upon replacement and filling with distilled H20 there was a lot of indication in coloring that there was a large volume of coolant left in the block/IC curcuit.
One would assume this would mean there are pockets that cannot drain in the block. I am unaware of any volume amounts though... Flush it once, drive around for the weekend, flush it again on Sunday and you should be good. That is assuming as well you are trying to flush all your old coolant out and replace it.
