For all you guys that believe you can never have too many tools, get yourself a Lisle #24680 spill free funnel. This thing worked awesome. Dash gauge back to barely above the warm line and heater was HOT! The most surprising thing to me was you can remove it from the rad with the coolant piping hot and not spill a drop. And the excess in the funnel right into the overflow. Obviously never had one, so I'm a little giddy with it.
