Running without a Thermostat

This is a myth...
*** I tend to agree with John here. I believe, that the requirement for a
thermostat body, or at least, a restrictor plate, is due to the type of pump
our cars use.
Essentially, a water pump is a rotating plate with short vanes on one side.
This does not seem like a very "positive action" mechanism to me. It depends
on the flow characteristics, viscosity, and mass of the water to work at all.
Imagine a large tank of water with such a rotating plate in the middle.
Would any net flow of water occur? I submit that all that would happen, would
be a bit of a whirlpool in the vicinity of the plate.
I believe that one of the requirements for proper operation of these
extremely simple pumps, is that it see a defined backpressure to work against.
This is provided by the hole in the thermostat.
