Do you think its possible to use a wet vac and just suck out the coolant out of the radiator versus removing the plug and draining?
You don't have a clue how a radiator and cooling system works, do you... that's OK, we all have to learn how things work... Short answer, NO. :nothappy:
Now: Study this, consider that a vacuum hose will only reach maybe,
maybe, the top inch or two of your radiator, and then try to imagine how it would be able to suck out all the liquid from the
entire system
and the engine block...
I guess a super-powerful vacuum could do it, if you opened up the lowest drain plug to allow air pressure to help void the entire system... but if you have to do
that anyhow...
you might as well drain it from the bottom like you're supposed to.
And now... Back to flights of imagination, like Transformer movies...
