a way to clean cooling system? w/ heads off

[Ceejkay]

Just as the title states, is there a way to clean all the coolant passages on the block with the heads off? i have the heads off already and judging by how much stop leak crap i found, i would like to make sure i get it out of the rest of the block before i put fresh heads on it.

nope, must have heads on to do a block flush.

You can drain it but once that stuff is in there you gotta hot tank it to clean it out ...
