Of course there is, I was just trying to point out the actual function of a thermostat which is to set a minimum temperature and aid in warm up. Since automotive water pumps are mechanical and vary based on RPM there needs to be something to restrict the flow to a level where it is actually being effective. It just happens that they build the restrictor into the thermostat.
