I know I will never dispel the myth Bill but you are incorrect that the internals will over heat.
You may not be able to cool a hot piece of metal by applying water to it(the water will turn to steam), but you will never get a piece of metal very worm it it is in contact with cool water first.
Could you tell me how the early cars and trucks managed to operate before thermostats were used?
I would also question you on why they sell high volume water pumps for high performance engines?
I don't want to come across as argumentative but this myth drives me crazy.
